Given numbers are 130, 715, 247, 851

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 715 are 5 x 11 x 13

Prime factors of 247 are 13 x 19

Prime factors of 851 are 23 x 37

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

Given numbers are 130, 715, 247, 851

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

Apply this formula for all numbers.

Step1:

LCM(130, 715) = 1430

GCD(130, 715) = ( 130 x 715 ) / 1430

= 130 / 715

= 130

Step2:

LCM(65, 247) = 1235

GCD(65, 247) = ( 65 x 247 ) / 1235

= 65 / 247

= 65

Step3:

LCM(13, 851) = 11063

GCD(13, 851) = ( 13 x 851 ) / 11063

= 13 / 851

= 13

So, Greatest Common Divisor of 130, 715, 247, 851 is 1
