Given numbers are 178, 857, 425, 172

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

Apply this formula for all numbers.

Step1:

LCM(178, 857) = 152546

GCD(178, 857) = ( 178 x 857 ) / 152546

= 178 / 857

= 178

Step2:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 178, 857, 425, 172 is 1
