GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 756) = 108108
GCD(429, 756) = ( 429 x 756 ) / 108108
= 429 / 756
= 429
Step2:
LCM(3, 891) = 891
GCD(3, 891) = ( 3 x 891 ) / 891
= 3 / 891
= 3
Step3:
LCM(3, 387) = 387
GCD(3, 387) = ( 3 x 387 ) / 387
= 3 / 387
= 3
So, Greatest Common Divisor of 429, 756, 891, 387 is 3
