Given numbers are 791, 637, 729, 407

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(791, 637) = 71981

GCD(791, 637) = ( 791 x 637 ) / 71981

= 791 / 637

= 791

Step2:

LCM(7, 729) = 5103

GCD(7, 729) = ( 7 x 729 ) / 5103

= 7 / 729

= 7

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 791, 637, 729, 407 is 1
