Given numbers are 134, 931, 645, 957
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(134, 931) = 124754
GCD(134, 931) = ( 134 x 931 ) / 124754
= 134 / 931
= 134
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 134, 931, 645, 957 is 1
