Given numbers are 429, 858, 840, 872
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, 840) = 120120
GCD(429, 840) = ( 429 x 840 ) / 120120
= 429 / 840
= 429
Step3:
LCM(3, 872) = 2616
GCD(3, 872) = ( 3 x 872 ) / 2616
= 3 / 872
= 3
So, Greatest Common Divisor of 429, 858, 840, 872 is 1
