Steps to Calculate GCD of 422, 554, 689, 145 using LCM Formula
Given numbers are 422, 554, 689, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 554) = 116894
GCD(422, 554) = ( 422 x 554 ) / 116894
= 422 / 554
= 422
Step2:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 422, 554, 689, 145 is 1
