Given numbers are 247, 441, 200, 161

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 161 are 7 x 23

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

Given numbers are 247, 441, 200, 161

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

Apply this formula for all numbers.

Step1:

LCM(247, 441) = 108927

GCD(247, 441) = ( 247 x 441 ) / 108927

= 247 / 441

= 247

Step2:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 247, 441, 200, 161 is 1
