Given numbers are 247, 141, 640, 484

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 141 are 3 x 47

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 484 are 2 x 2 x 11 x 11

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

Given numbers are 247, 141, 640, 484

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

Apply this formula for all numbers.

Step1:

LCM(247, 141) = 34827

GCD(247, 141) = ( 247 x 141 ) / 34827

= 247 / 141

= 247

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

So, Greatest Common Divisor of 247, 141, 640, 484 is 1
