The list of prime factors of all numbers are
Prime factors of 133 are 7 x 19
Prime factors of 470 are 2 x 5 x 47
Prime factors of 645 are 3 x 5 x 43
Prime factors of 129 are 3 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 133, 470, 645, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(133, 470) = 62510
GCD(133, 470) = ( 133 x 470 ) / 62510
= 133 / 470
= 133
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 133, 470, 645, 129 is 1
