Steps to Calculate GCD of 638, 715, 453, 439 using LCM Formula
Given numbers are 638, 715, 453, 439
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 715) = 41470
GCD(638, 715) = ( 638 x 715 ) / 41470
= 638 / 715
= 638
Step2:
LCM(11, 453) = 4983
GCD(11, 453) = ( 11 x 453 ) / 4983
= 11 / 453
= 11
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 638, 715, 453, 439 is 1
