Given numbers are 438, 695, 426

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

Apply this formula for all numbers.

Step1:

LCM(438, 695) = 304410

GCD(438, 695) = ( 438 x 695 ) / 304410

= 438 / 695

= 438

Step2:

LCM(1, 426) = 426

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

= 1 / 426

= 1

So, Greatest Common Divisor of 438, 695, 426 is 1
