GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 594) = 127710
GCD(645, 594) = ( 645 x 594 ) / 127710
= 645 / 594
= 645
Step2:
LCM(3, 462) = 462
GCD(3, 462) = ( 3 x 462 ) / 462
= 3 / 462
= 3
Step3:
LCM(3, 868) = 2604
GCD(3, 868) = ( 3 x 868 ) / 2604
= 3 / 868
= 3
So, Greatest Common Divisor of 645, 594, 462, 868 is 1
