Given numbers are 428, 344, 695, 676

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

Apply this formula for all numbers.

Step1:

LCM(428, 344) = 36808

GCD(428, 344) = ( 428 x 344 ) / 36808

= 428 / 344

= 428

Step2:

LCM(4, 695) = 2780

GCD(4, 695) = ( 4 x 695 ) / 2780

= 4 / 695

= 4

Step3:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

So, Greatest Common Divisor of 428, 344, 695, 676 is 1
