Given numbers are 251, 440, 530, 428
The list of prime factors of all numbers are
Prime factors of 251 are 251
Prime factors of 440 are 2 x 2 x 2 x 5 x 11
Prime factors of 530 are 2 x 5 x 53
Prime factors of 428 are 2 x 2 x 107
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 251, 440, 530, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 440) = 110440
GCD(251, 440) = ( 251 x 440 ) / 110440
= 251 / 440
= 251
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 251, 440, 530, 428 is 1
