Given numbers are 400, 656, 417, 324
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 656 are 2 x 2 x 2 x 2 x 41
Prime factors of 417 are 3 x 139
Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 656, 417, 324
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 656) = 16400
GCD(400, 656) = ( 400 x 656 ) / 16400
= 400 / 656
= 400
Step2:
LCM(16, 417) = 6672
GCD(16, 417) = ( 16 x 417 ) / 6672
= 16 / 417
= 16
Step3:
LCM(1, 324) = 324
GCD(1, 324) = ( 1 x 324 ) / 324
= 1 / 324
= 1
So, Greatest Common Divisor of 400, 656, 417, 324 is 1
