Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7
Prime factors of 477 are 3 x 3 x 53
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 254, 122, 756, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(254, 122) = 15494
GCD(254, 122) = ( 254 x 122 ) / 15494
= 254 / 122
= 254
Step2:
LCM(2, 756) = 756
GCD(2, 756) = ( 2 x 756 ) / 756
= 2 / 756
= 2
Step3:
LCM(2, 477) = 954
GCD(2, 477) = ( 2 x 477 ) / 954
= 2 / 477
= 2
So, Greatest Common Divisor of 254, 122, 756, 477 is 1
