Given numbers are 438, 196, 434, 124

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

Apply this formula for all numbers.

Step1:

LCM(438, 196) = 42924

GCD(438, 196) = ( 438 x 196 ) / 42924

= 438 / 196

= 438

Step2:

LCM(2, 434) = 434

GCD(2, 434) = ( 2 x 434 ) / 434

= 2 / 434

= 2

Step3:

LCM(2, 124) = 124

GCD(2, 124) = ( 2 x 124 ) / 124

= 2 / 124

= 2

So, Greatest Common Divisor of 438, 196, 434, 124 is 2
