Steps to Calculate GCD of 677, 436, 135, 649 using LCM Formula
Given numbers are 677, 436, 135, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 436) = 295172
GCD(677, 436) = ( 677 x 436 ) / 295172
= 677 / 436
= 677
Step2:
LCM(1, 135) = 135
GCD(1, 135) = ( 1 x 135 ) / 135
= 1 / 135
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 677, 436, 135, 649 is 1
