Given numbers are 247, 295, 220, 213

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 295 are 5 x 59

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 213 are 3 x 71

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

Given numbers are 247, 295, 220, 213

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

Apply this formula for all numbers.

Step1:

LCM(247, 295) = 72865

GCD(247, 295) = ( 247 x 295 ) / 72865

= 247 / 295

= 247

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 213) = 213

GCD(1, 213) = ( 1 x 213 ) / 213

= 1 / 213

= 1

So, Greatest Common Divisor of 247, 295, 220, 213 is 1
