Given numbers are 649, 665, 589, 791

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

Apply this formula for all numbers.

Step1:

LCM(649, 665) = 431585

GCD(649, 665) = ( 649 x 665 ) / 431585

= 649 / 665

= 649

Step2:

LCM(1, 589) = 589

GCD(1, 589) = ( 1 x 589 ) / 589

= 1 / 589

= 1

Step3:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

So, Greatest Common Divisor of 649, 665, 589, 791 is 1
