Given numbers are 391, 130, 178

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

Apply this formula for all numbers.

Step1:

LCM(391, 130) = 50830

GCD(391, 130) = ( 391 x 130 ) / 50830

= 391 / 130

= 391

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 391, 130, 178 is 1
