Given numbers are 438, 173, 656

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

Apply this formula for all numbers.

Step1:

LCM(438, 173) = 75774

GCD(438, 173) = ( 438 x 173 ) / 75774

= 438 / 173

= 438

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 438, 173, 656 is 1
