Given numbers are 124, 660, 123, 510
The list of prime factors of all numbers are
Prime factors of 124 are 2 x 2 x 31
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 123 are 3 x 41
Prime factors of 510 are 2 x 3 x 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 124, 660, 123, 510
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 660) = 20460
GCD(124, 660) = ( 124 x 660 ) / 20460
= 124 / 660
= 124
Step2:
LCM(4, 123) = 492
GCD(4, 123) = ( 4 x 123 ) / 492
= 4 / 123
= 4
Step3:
LCM(1, 510) = 510
GCD(1, 510) = ( 1 x 510 ) / 510
= 1 / 510
= 1
So, Greatest Common Divisor of 124, 660, 123, 510 is 1
