Given numbers are 438, 148, 205

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

Apply this formula for all numbers.

Step1:

LCM(438, 148) = 32412

GCD(438, 148) = ( 438 x 148 ) / 32412

= 438 / 148

= 438

Step2:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

So, Greatest Common Divisor of 438, 148, 205 is 1
