GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 622) = 428558
GCD(689, 622) = ( 689 x 622 ) / 428558
= 689 / 622
= 689
Step2:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
Step3:
LCM(1, 312) = 312
GCD(1, 312) = ( 1 x 312 ) / 312
= 1 / 312
= 1
So, Greatest Common Divisor of 689, 622, 451, 312 is 1
