Given numbers are 686, 772, 506, 651

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

Apply this formula for all numbers.

Step1:

LCM(686, 772) = 264796

GCD(686, 772) = ( 686 x 772 ) / 264796

= 686 / 772

= 686

Step2:

LCM(2, 506) = 506

GCD(2, 506) = ( 2 x 506 ) / 506

= 2 / 506

= 2

Step3:

LCM(2, 651) = 1302

GCD(2, 651) = ( 2 x 651 ) / 1302

= 2 / 651

= 2

So, Greatest Common Divisor of 686, 772, 506, 651 is 1
