Steps to Calculate GCD of 407, 689, 131, 961 using LCM Formula
Given numbers are 407, 689, 131, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 689) = 280423
GCD(407, 689) = ( 407 x 689 ) / 280423
= 407 / 689
= 407
Step2:
LCM(1, 131) = 131
GCD(1, 131) = ( 1 x 131 ) / 131
= 1 / 131
= 1
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 407, 689, 131, 961 is 1
