HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers. For example, consider the numbers 30 (2 x 3 x 5), 36 (2 x 2 x 3 x 3), 42 (2 x 3 x 7), 45 (3 x 3 x 5). 3 is the largest number that divides each of these numbers, and hence, is the HCF for these numbers.
When might you use HCF and LCM in real life?
1) To split things into smaller sections. 2) To equally distribute 2 or more sets of items into their largest grouping. 3) To figure out how many people we can invite for a party.
Why HCF is useful?
To split things into smaller sections. To equally distribute any number of sets of items into their largest grouping. To figure out how many people we can invite. To arrange something into rows or groups.
Which is the best example of HCF in real life?
1) About an event that is or will be repeating over and over. 2) To purchase or get multiple items in order to have enough. 3) To figure out when something will happen again at the same time. Real life example : Ram exercises every 12 days and Deepika every 8 days. Ram and Deepika both exercised today.
How can GCF be used in real life?
We use greatest common factors all the time with fractions, and as fractions are used a lot in everyday life, this makes GCF very useful! By finding the GCF of the denominator and numerator, you can then successfully simplify a fraction or ratio. E.g. We can simplify 30 45 by knowing that its HCF is 15.
How to find the highest common factor in HCF?
Then multiply each factor the most number of times it occurs in any number. If the same multiple occurs more than once in both the given numbers, then multiply the factor the most number of times it occurs. In BYJU’S you can also learn, Prime Factorization Of Hcf And Lcm. Example: Find the Highest Common Factor of 25, 35 and 45.
Which is the best example of H.C.F?
H.C.F. : We use H.C.F. method where we need : 1) To split things into smaller sections? 2) To equally distribute 2 or more sets of items into their largest grouping? 3) To figure out how many people we can invite? 4) To arrange something into rows or groups? Real life example : Priyanka has two pieces of cloth.
