Given numbers are 461, 240, 247, 221

The list of prime factors of all numbers are

Prime factors of 461 are 461

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 247 are 13 x 19

Prime factors of 221 are 13 x 17

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

Given numbers are 461, 240, 247, 221

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

Apply this formula for all numbers.

Step1:

LCM(461, 240) = 110640

GCD(461, 240) = ( 461 x 240 ) / 110640

= 461 / 240

= 461

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 461, 240, 247, 221 is 1
