Steps to Calculate GCD of 429, 858, 128, 577 using LCM Formula

Given numbers are 429, 858, 128, 577

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(429, 858) = 858

GCD(429, 858) = ( 429 x 858 ) / 858

= 429 / 858

= 429


Step2:

LCM(429, 128) = 54912

GCD(429, 128) = ( 429 x 128 ) / 54912

= 429 / 128

= 429


Step3:

LCM(1, 577) = 577

GCD(1, 577) = ( 1 x 577 ) / 577

= 1 / 577

= 1


So, Greatest Common Divisor of 429, 858, 128, 577 is 1
