Given numbers are 142, 320, 172

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

Apply this formula for all numbers.

Step1:

LCM(142, 320) = 22720

GCD(142, 320) = ( 142 x 320 ) / 22720

= 142 / 320

= 142

Step2:

LCM(2, 172) = 172

GCD(2, 172) = ( 2 x 172 ) / 172

= 2 / 172

= 2

So, Greatest Common Divisor of 142, 320, 172 is 2
