Given numbers are 210, 291, 287

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 291 are 3 x 97

Prime factors of 287 are 7 x 41

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 210, 291, 287

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

Apply this formula for all numbers.

Step1:

LCM(210, 291) = 20370

GCD(210, 291) = ( 210 x 291 ) / 20370

= 210 / 291

= 210

Step2:

LCM(3, 287) = 861

GCD(3, 287) = ( 3 x 287 ) / 861

= 3 / 287

= 3

So, Greatest Common Divisor of 210, 291, 287 is 1
