Given numbers are 791, 517, 688, 415
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 517) = 408947
GCD(791, 517) = ( 791 x 517 ) / 408947
= 791 / 517
= 791
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
So, Greatest Common Divisor of 791, 517, 688, 415 is 1
