Given numbers are 625, 153, 391

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

Apply this formula for all numbers.

Step1:

LCM(625, 153) = 95625

GCD(625, 153) = ( 625 x 153 ) / 95625

= 625 / 153

= 625

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 625, 153, 391 is 1
