Given numbers are 530, 635, 428, 123
The list of prime factors of all numbers are
Prime factors of 530 are 2 x 5 x 53
Prime factors of 635 are 5 x 127
Prime factors of 428 are 2 x 2 x 107
Prime factors of 123 are 3 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 530, 635, 428, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 635) = 67310
GCD(530, 635) = ( 530 x 635 ) / 67310
= 530 / 635
= 530
Step2:
LCM(5, 428) = 2140
GCD(5, 428) = ( 5 x 428 ) / 2140
= 5 / 428
= 5
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 530, 635, 428, 123 is 1
