GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 675) = 500850
GCD(742, 675) = ( 742 x 675 ) / 500850
= 742 / 675
= 742
Step2:
LCM(1, 379) = 379
GCD(1, 379) = ( 1 x 379 ) / 379
= 1 / 379
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 742, 675, 379, 645 is 1
