Given numbers are 438, 428, 347, 199

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

Apply this formula for all numbers.

Step1:

LCM(438, 428) = 93732

GCD(438, 428) = ( 438 x 428 ) / 93732

= 438 / 428

= 438

Step2:

LCM(2, 347) = 694

GCD(2, 347) = ( 2 x 347 ) / 694

= 2 / 347

= 2

Step3:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 438, 428, 347, 199 is 1
