Given numbers are 654, 431, 438

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

Apply this formula for all numbers.

Step1:

LCM(654, 431) = 281874

GCD(654, 431) = ( 654 x 431 ) / 281874

= 654 / 431

= 654

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 654, 431, 438 is 1
