Therefore, the greatest common factor of 4 and 10 is 2. Example 2: The product of two numbers is 40. If their GCF is 2, what is their LCM? Therefore, the LCM is 20.
What is the least common multiple of 9 7 and 6?
126
What is the LCM of 6, 7, and 9? Answer: LCM of 6, 7, and 9 is 126.
How do you find the LCM of 4 and 7?
Answer: LCM of 4 and 7 is 28.
What is the HCF of 4 and 10?
2
Answer: HCF of 4 and 10 is 2.
What is the HCF of 4/10 and 20?
HCF of 4 and 20 by Prime Factorization As visible, 4 and 20 have common prime factors. Hence, the HCF of 4 and 20 is 2 × 2 = 4.
Which is the least common multiple of 4 and 7?
4: 4,8,12,16,20,24,28,32,36,40,44,48,52,56… 7: 7,14,21,28,35,42,49,56,63,70,77… Then you find the first number which 4 and 7 have in common. 4 and 7 have 28 and 56 in common BUT the LCM would be 28 since that’s the LEAST common, or the smallest number that they would have in common. Hope this helped!
Which is the LCM of 4, 7 and 10?
This method consists of listing the multiples of all the numbers that we want to find the LCM. Multiples of a number are calculated by multiplying that number by the natural numbers 2, 3, 4., etc. See below: Because 140 is the first number to appear on both lists of multiples, 140 is the LCM of 4, 7 and 10.
What is the lowest common factor of 4 and 10?
Least common multiple (LCM) of 4 and 10 is 20. LCM(4,10) = 20. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
Which is the least common multiple of two numbers?
For example, LCM (2,3) = 6 and LCM (6,10) = 30. For the least common multiple of more than 2 numbers, say a, b, c and d, it is the smallest integer that is evenly divisible by all numbers and can be calculated such that LCM (a,b,c,d) = LCM ( LCM ( LCM ( a,b ), c ), d ).
