Steps to Calculate GCD of 221, 497, 655, 631 using LCM Formula
Given numbers are 221, 497, 655, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 497) = 109837
GCD(221, 497) = ( 221 x 497 ) / 109837
= 221 / 497
= 221
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 221, 497, 655, 631 is 1
