LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
The highest common factor (HCF) of 12 and 42 is the largest number that divides both 12 and 42 without leaving a remainder. To find the HCF, we need to determine the common factors of 12 and 42, which are 1, 2, 3, and 6. The highest common factor of 12 and 42 is 6.
hcf(12, 36, 42) = 6 12 = 22 x 3 36 = 22 x 32 42 = 2 x 3 x 7 hcf = 2 x 3 = 6
The GCF is 42.
It is: 14
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
hcf(12, 36, 42) = 6 12 = 22 x 3 36 = 22 x 32 42 = 2 x 3 x 7 hcf = 2 x 3 = 6
The HCF of 124 and 72 is 4.
hcf = 42, lcm = 84.
The GCF is 42.
