Given numbers are 515, 721, 689, 973
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 721) = 3605
GCD(515, 721) = ( 515 x 721 ) / 3605
= 515 / 721
= 515
Step2:
LCM(103, 689) = 70967
GCD(103, 689) = ( 103 x 689 ) / 70967
= 103 / 689
= 103
Step3:
LCM(1, 973) = 973
GCD(1, 973) = ( 1 x 973 ) / 973
= 1 / 973
= 1
So, Greatest Common Divisor of 515, 721, 689, 973 is 1
