Steps to Calculate GCD of 961, 655, 76, 649 using LCM Formula
Given numbers are 961, 655, 76, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 655) = 629455
GCD(961, 655) = ( 961 x 655 ) / 629455
= 961 / 655
= 961
Step2:
LCM(1, 76) = 76
GCD(1, 76) = ( 1 x 76 ) / 76
= 1 / 76
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 961, 655, 76, 649 is 1
