Given numbers are 453, 621, 617, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(453, 621) = 93771
GCD(453, 621) = ( 453 x 621 ) / 93771
= 453 / 621
= 453
Step2:
LCM(3, 617) = 1851
GCD(3, 617) = ( 3 x 617 ) / 1851
= 3 / 617
= 3
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 453, 621, 617, 668 is 1
