Given numbers are 251, 705, 646

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

Apply this formula for all numbers.

Step1:

LCM(251, 705) = 176955

GCD(251, 705) = ( 251 x 705 ) / 176955

= 251 / 705

= 251

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 251, 705, 646 is 1
