Steps to Calculate GCD of 957, 987, 13, 395 using LCM Formula
Given numbers are 957, 987, 13, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(957, 987) = 314853
GCD(957, 987) = ( 957 x 987 ) / 314853
= 957 / 987
= 957
Step2:
LCM(3, 13) = 39
GCD(3, 13) = ( 3 x 13 ) / 39
= 3 / 13
= 3
Step3:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
So, Greatest Common Divisor of 957, 987, 13, 395 is 1
