Given numbers are 717, 394, 549, 644

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

Apply this formula for all numbers.

Step1:

LCM(717, 394) = 282498

GCD(717, 394) = ( 717 x 394 ) / 282498

= 717 / 394

= 717

Step2:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 717, 394, 549, 644 is 1
