Given numbers are 981, 172, 290

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

Apply this formula for all numbers.

Step1:

LCM(981, 172) = 168732

GCD(981, 172) = ( 981 x 172 ) / 168732

= 981 / 172

= 981

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 981, 172, 290 is 1
