Given numbers are 724, 746, 485, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(724, 746) = 270052
GCD(724, 746) = ( 724 x 746 ) / 270052
= 724 / 746
= 724
Step2:
LCM(2, 485) = 970
GCD(2, 485) = ( 2 x 485 ) / 970
= 2 / 485
= 2
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 724, 746, 485, 689 is 1
