Given numbers are 126, 175, 137, 721
The list of prime factors of all numbers are
Prime factors of 126 are 2 x 3 x 3 x 7
Prime factors of 175 are 5 x 5 x 7
Prime factors of 137 are 137
Prime factors of 721 are 7 x 103
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 126, 175, 137, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 175) = 3150
GCD(126, 175) = ( 126 x 175 ) / 3150
= 126 / 175
= 126
Step2:
LCM(7, 137) = 959
GCD(7, 137) = ( 7 x 137 ) / 959
= 7 / 137
= 7
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 126, 175, 137, 721 is 1
