Given numbers are 130, 420, 917, 247

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 917 are 7 x 131

Prime factors of 247 are 13 x 19

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

Given numbers are 130, 420, 917, 247

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

Apply this formula for all numbers.

Step1:

LCM(130, 420) = 5460

GCD(130, 420) = ( 130 x 420 ) / 5460

= 130 / 420

= 130

Step2:

LCM(10, 917) = 9170

GCD(10, 917) = ( 10 x 917 ) / 9170

= 10 / 917

= 10

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 130, 420, 917, 247 is 1
