Steps to Calculate GCD of 749, 687, 991, 157 using LCM Formula
Given numbers are 749, 687, 991, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 687) = 514563
GCD(749, 687) = ( 749 x 687 ) / 514563
= 749 / 687
= 749
Step2:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 749, 687, 991, 157 is 1
