What factors do 6 and 7 have in common?
The gcf of 6 and 7 can be obtained like this:
- The factors of 6 are 6, 3, 2, 1.
- The factors of 7 are 7, 1.
- The common factors of 6 and 7 are 1, intersecting the two sets above.
- In the intersection factors of 6 ∩ factors of 7 the greatest element is 1.
- Therefore, the greatest common factor of 6 and 7 is 1.
What is the smallest multiple of 3 and 6?
What is the LCM of 3 and 6? The LCM of 3 and 6 is 6.
Which is the least common multiple of 3, 6, and 7?
There is a simple way to figure out the lowest common multiple of any few numbers. Step 1. Prime factorise all the numbers. In this example, you have the numbers 3, 6 and 7. 3 is already a prime number by itself so 3=3. 6 = 2*3. 7 is again, also a prime number by itself, so 7=7.
What does each set of 3 have in common?
All are cracked 2. There are seven of each 3. All are carved 1. All are smallest of their kind 2. All are tuned 3. All have capes Did you get them all right? SHARE this fun brainteaser so your friends and family can play along too!
Which is the LCM for 6 and 7?
That means the LCM of 6 and 7 is 6*7, which is 42. Since 6 is a multiple of 3, all multiples of 6 are also multiples of 3, and thus 42 is also a multiple of 3 and is the LCM for 3, 6, and 7. Unless the digits in a number add up to a multiple of 3, that number is not a multiple of 3.
Is there a factor of 3 in 7?
Unlike 6, there is no factor of 3 in 7 and so not every multiple of 7 has a factor of 3: in order to be a multiple of both 3 and 7, a number must be a multiple of 21. One important difference in the multiples of 6 and 7 that appear in the list of multiples of 3 is that every multiple of 6 is also a multiple of 3.
