Given numbers are 686, 917, 862, 766

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

Apply this formula for all numbers.

Step1:

LCM(686, 917) = 89866

GCD(686, 917) = ( 686 x 917 ) / 89866

= 686 / 917

= 686

Step2:

LCM(7, 862) = 6034

GCD(7, 862) = ( 7 x 862 ) / 6034

= 7 / 862

= 7

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 686, 917, 862, 766 is 1
