Given numbers are 247, 760, 455, 731

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 455 are 5 x 7 x 13

Prime factors of 731 are 17 x 43

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

Given numbers are 247, 760, 455, 731

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

Apply this formula for all numbers.

Step1:

LCM(247, 760) = 9880

GCD(247, 760) = ( 247 x 760 ) / 9880

= 247 / 760

= 247

Step2:

LCM(19, 455) = 8645

GCD(19, 455) = ( 19 x 455 ) / 8645

= 19 / 455

= 19

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 247, 760, 455, 731 is 1
