Given numbers are 401, 100, 177, 646
The list of prime factors of all numbers are
Prime factors of 401 are 401
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 177 are 3 x 59
Prime factors of 646 are 2 x 17 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 401, 100, 177, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 100) = 40100
GCD(401, 100) = ( 401 x 100 ) / 40100
= 401 / 100
= 401
Step2:
LCM(1, 177) = 177
GCD(1, 177) = ( 1 x 177 ) / 177
= 1 / 177
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 401, 100, 177, 646 is 1
