Given numbers are 242, 856, 438

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

Apply this formula for all numbers.

Step1:

LCM(242, 856) = 103576

GCD(242, 856) = ( 242 x 856 ) / 103576

= 242 / 856

= 242

Step2:

LCM(2, 438) = 438

GCD(2, 438) = ( 2 x 438 ) / 438

= 2 / 438

= 2

So, Greatest Common Divisor of 242, 856, 438 is 2
