Given numbers are 640, 401, 758, 678
The list of prime factors of all numbers are
Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 401 are 401
Prime factors of 758 are 2 x 379
Prime factors of 678 are 2 x 3 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 640, 401, 758, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 401) = 256640
GCD(640, 401) = ( 640 x 401 ) / 256640
= 640 / 401
= 640
Step2:
LCM(1, 758) = 758
GCD(1, 758) = ( 1 x 758 ) / 758
= 1 / 758
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 640, 401, 758, 678 is 1
