The least common factor of any set of numbers is 1.
No on both counts. 4 is not prime and 4 is not a factor of 30.
There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.
No because 4 is not a factor of 30
36
1, 2 and 4
30 is divisible by 5, but not by 4. So 5 is the factor of 30, but 4 is not.
No because 4 cannot be evenly divided into 30
The greatest common factor of 33 and 92 is 1.
The GCF of 4, 30 and 42 is 2.
Factors of 4: 1, 2, 4 Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 Compare. Greatest common factor is 2.
It is 1
5 times 12 is 60, and 4 times 15 is 60. Since 5 and 4 do not have a common factor other than 1, 60 is is the least common multiple of 12 and 15.
