Given numbers are 817, 657, 997, 749

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

Apply this formula for all numbers.

Step1:

LCM(817, 657) = 536769

GCD(817, 657) = ( 817 x 657 ) / 536769

= 817 / 657

= 817

Step2:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 817, 657, 997, 749 is 1
