6
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
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.
The highest or greatest common factor of 420 and 294 is 42.
