Steps to Calculate GCD of 561, 341, 157, 709 using LCM Formula
Given numbers are 561, 341, 157, 709
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 341) = 17391
GCD(561, 341) = ( 561 x 341 ) / 17391
= 561 / 341
= 561
Step2:
LCM(11, 157) = 1727
GCD(11, 157) = ( 11 x 157 ) / 1727
= 11 / 157
= 11
Step3:
LCM(1, 709) = 709
GCD(1, 709) = ( 1 x 709 ) / 709
= 1 / 709
= 1
So, Greatest Common Divisor of 561, 341, 157, 709 is 1
