Given numbers are 221, 147, 918, 248

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 147 are 3 x 7 x 7

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 248 are 2 x 2 x 2 x 31

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

Given numbers are 221, 147, 918, 248

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

Apply this formula for all numbers.

Step1:

LCM(221, 147) = 32487

GCD(221, 147) = ( 221 x 147 ) / 32487

= 221 / 147

= 221

Step2:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 221, 147, 918, 248 is 1
