Given numbers are 155, 357, 872

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

Apply this formula for all numbers.

Step1:

LCM(155, 357) = 55335

GCD(155, 357) = ( 155 x 357 ) / 55335

= 155 / 357

= 155

Step2:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 155, 357, 872 is 1
