Steps to Calculate GCD of 325, 139, 497, 561 using LCM Formula
Given numbers are 325, 139, 497, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(325, 139) = 45175
GCD(325, 139) = ( 325 x 139 ) / 45175
= 325 / 139
= 325
Step2:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 325, 139, 497, 561 is 1
