Given numbers are 426, 878, 868, 657

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

Apply this formula for all numbers.

Step1:

LCM(426, 878) = 187014

GCD(426, 878) = ( 426 x 878 ) / 187014

= 426 / 878

= 426

Step2:

LCM(2, 868) = 868

GCD(2, 868) = ( 2 x 868 ) / 868

= 2 / 868

= 2

Step3:

LCM(2, 657) = 1314

GCD(2, 657) = ( 2 x 657 ) / 1314

= 2 / 657

= 2

So, Greatest Common Divisor of 426, 878, 868, 657 is 1
