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

Apply this formula for all numbers.

Step1:

LCM(438, 381) = 55626

GCD(438, 381) = ( 438 x 381 ) / 55626

= 438 / 381

= 438

Step2:

LCM(3, 973) = 2919

GCD(3, 973) = ( 3 x 973 ) / 2919

= 3 / 973

= 3

So, Greatest Common Divisor of 438, 381, 973 is 1
