Given numbers are 642, 364, 613, 591
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 364) = 116844
GCD(642, 364) = ( 642 x 364 ) / 116844
= 642 / 364
= 642
Step2:
LCM(2, 613) = 1226
GCD(2, 613) = ( 2 x 613 ) / 1226
= 2 / 613
= 2
Step3:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
So, Greatest Common Divisor of 642, 364, 613, 591 is 1
