Steps to Calculate GCD of 458, 221, 631, 407 using LCM Formula
Given numbers are 458, 221, 631, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 221) = 101218
GCD(458, 221) = ( 458 x 221 ) / 101218
= 458 / 221
= 458
Step2:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 458, 221, 631, 407 is 1
