Given numbers are 530, 120, 244, 687
The list of prime factors of all numbers are
Prime factors of 530 are 2 x 5 x 53
Prime factors of 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 244 are 2 x 2 x 61
Prime factors of 687 are 3 x 229
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 530, 120, 244, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 120) = 6360
GCD(530, 120) = ( 530 x 120 ) / 6360
= 530 / 120
= 530
Step2:
LCM(10, 244) = 1220
GCD(10, 244) = ( 10 x 244 ) / 1220
= 10 / 244
= 10
Step3:
LCM(2, 687) = 1374
GCD(2, 687) = ( 2 x 687 ) / 1374
= 2 / 687
= 2
So, Greatest Common Divisor of 530, 120, 244, 687 is 1
