GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(451, 689) = 310739
GCD(451, 689) = ( 451 x 689 ) / 310739
= 451 / 689
= 451
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 928) = 928
GCD(1, 928) = ( 1 x 928 ) / 928
= 1 / 928
= 1
So, Greatest Common Divisor of 451, 689, 621, 928 is 1
