Given numbers are 126, 129, 121, 151
The list of prime factors of all numbers are
Prime factors of 126 are 2 x 3 x 3 x 7
Prime factors of 129 are 3 x 43
Prime factors of 121 are 11 x 11
Prime factors of 151 are 151
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 126, 129, 121, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 129) = 5418
GCD(126, 129) = ( 126 x 129 ) / 5418
= 126 / 129
= 126
Step2:
LCM(3, 121) = 363
GCD(3, 121) = ( 3 x 121 ) / 363
= 3 / 121
= 3
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 126, 129, 121, 151 is 1
