Given numbers are 354, 387, 56, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(354, 387) = 45666
GCD(354, 387) = ( 354 x 387 ) / 45666
= 354 / 387
= 354
Step2:
LCM(3, 56) = 168
GCD(3, 56) = ( 3 x 56 ) / 168
= 3 / 56
= 3
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 354, 387, 56, 643 is 1
