Given numbers are 130, 147, 756, 245

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 147 are 3 x 7 x 7

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 130, 147, 756, 245

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

Apply this formula for all numbers.

Step1:

LCM(130, 147) = 19110

GCD(130, 147) = ( 130 x 147 ) / 19110

= 130 / 147

= 130

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 130, 147, 756, 245 is 1
