Steps to Calculate GCD of 634, 438, 75, 435 using LCM Formula
Given numbers are 634, 438, 75, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(634, 438) = 138846
GCD(634, 438) = ( 634 x 438 ) / 138846
= 634 / 438
= 634
Step2:
LCM(2, 75) = 150
GCD(2, 75) = ( 2 x 75 ) / 150
= 2 / 75
= 2
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 634, 438, 75, 435 is 1
