Given numbers are 665, 305, 724, 317

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

Apply this formula for all numbers.

Step1:

LCM(665, 305) = 40565

GCD(665, 305) = ( 665 x 305 ) / 40565

= 665 / 305

= 665

Step2:

LCM(5, 724) = 3620

GCD(5, 724) = ( 5 x 724 ) / 3620

= 5 / 724

= 5

Step3:

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

= 1 / 317

= 1

So, Greatest Common Divisor of 665, 305, 724, 317 is 1
