GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 603) = 129042
GCD(642, 603) = ( 642 x 603 ) / 129042
= 642 / 603
= 642
Step2:
LCM(3, 693) = 693
GCD(3, 693) = ( 3 x 693 ) / 693
= 3 / 693
= 3
Step3:
LCM(3, 329) = 987
GCD(3, 329) = ( 3 x 329 ) / 987
= 3 / 329
= 3
So, Greatest Common Divisor of 642, 603, 693, 329 is 1
