Given numbers are 645, 638, 453, 692
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 638) = 411510
GCD(645, 638) = ( 645 x 638 ) / 411510
= 645 / 638
= 645
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 692) = 692
GCD(1, 692) = ( 1 x 692 ) / 692
= 1 / 692
= 1
So, Greatest Common Divisor of 645, 638, 453, 692 is 1
