Answer for both. and explain how you got the answer so i can understand

Multiples : these are what we get after multiplying a number by an integer (not a decimal or fraction)
Example : 6 * 1 = 66 * 2 = 126 * 3 = 18so 6,12, and 18 are multiples of 6.

factors : these are what we multiply by to get a number
Example : 1 * 6 = 6so 1 and 6 are factors of 62 * 3 = 6 ...so 2 and 3 are also factors of 6

problem 1 : Look at ur clues...each number is less then or equal to 12this right here eliminates D because of the 15. The greatest common factor of the 2 numbers is 2and this eliminates B because if it has a factor of 2, it has to be an even number. So that leaves us with :
A. 6 and 10
C. 10 and 12
last cluethey have a least common multiple of 60...this means that ur 2 numbers cant have any other common multiples until 60.
6 * 10both are multiples of 60...however, they are also both multiples of 30...so 60 is not the least common multiple of 6 and 10, it is 30.
Therefore, ur answer is C. 10 and 12with the LCM of 60, LCF of 2 and < or = to 12

problem 2 : GCF (greatest common factor) of 42 and 84

factors of 42 : 1,2,3,6,7,14,21,42
factors of 84 : 1,2,3,4,6,7,12,14,21,28,42,84

therefore, the GCF of these 2 numbers is 42

Are there any statements?
