The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
It is 1 but the highest common factor is 6
The Greatest Common Factor (GCF) is: 6
The factors of 30 are 2, 3, and 5 The factors of 42 are 2, 3, and 7 So, the highest common factor will be 2 x 3 = 6
The greatest common factor of 12 and 42 is 6.12 and 42's highest common factor is six.
highest common factor is 6
Highest common factor is 7.
Highest common factor of 36, 42, and 54 is 6.
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
Yes 6 is the highest common factor of 42 and 48
The greatest common factor of the numbers 12 and 42 is 6.
18 and 42's highest common factor is six.
