Given numbers are 686, 961, 164, 562

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

Apply this formula for all numbers.

Step1:

LCM(686, 961) = 659246

GCD(686, 961) = ( 686 x 961 ) / 659246

= 686 / 961

= 686

Step2:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

Step3:

LCM(1, 562) = 562

GCD(1, 562) = ( 1 x 562 ) / 562

= 1 / 562

= 1

So, Greatest Common Divisor of 686, 961, 164, 562 is 1
