GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 660) = 70620
GCD(642, 660) = ( 642 x 660 ) / 70620
= 642 / 660
= 642
Step2:
LCM(6, 322) = 966
GCD(6, 322) = ( 6 x 322 ) / 966
= 6 / 322
= 6
Step3:
LCM(2, 369) = 738
GCD(2, 369) = ( 2 x 369 ) / 738
= 2 / 369
= 2
So, Greatest Common Divisor of 642, 660, 322, 369 is 1
