Given numbers are 856, 551, 426

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

Apply this formula for all numbers.

Step1:

LCM(856, 551) = 471656

GCD(856, 551) = ( 856 x 551 ) / 471656

= 856 / 551

= 856

Step2:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 856, 551, 426 is 1
