Steps to Calculate GCD of 421, 505, 491, 634 using LCM Formula
Given numbers are 421, 505, 491, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 505) = 212605
GCD(421, 505) = ( 421 x 505 ) / 212605
= 421 / 505
= 421
Step2:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 421, 505, 491, 634 is 1
