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
