Given numbers are 438, 778, 417

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

Apply this formula for all numbers.

Step1:

LCM(438, 778) = 170382

GCD(438, 778) = ( 438 x 778 ) / 170382

= 438 / 778

= 438

Step2:

LCM(2, 417) = 834

GCD(2, 417) = ( 2 x 417 ) / 834

= 2 / 417

= 2

So, Greatest Common Divisor of 438, 778, 417 is 1
