Given numbers are 401, 530, 639, 845
The list of prime factors of all numbers are
Prime factors of 401 are 401
Prime factors of 530 are 2 x 5 x 53
Prime factors of 639 are 3 x 3 x 71
Prime factors of 845 are 5 x 13 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 401, 530, 639, 845
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 530) = 212530
GCD(401, 530) = ( 401 x 530 ) / 212530
= 401 / 530
= 401
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 845) = 845
GCD(1, 845) = ( 1 x 845 ) / 845
= 1 / 845
= 1
So, Greatest Common Divisor of 401, 530, 639, 845 is 1
