Given numbers are 130, 685, 101, 455

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 685 are 5 x 137

Prime factors of 101 are 101

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 130, 685, 101, 455

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

Apply this formula for all numbers.

Step1:

LCM(130, 685) = 17810

GCD(130, 685) = ( 130 x 685 ) / 17810

= 130 / 685

= 130

Step2:

LCM(5, 101) = 505

GCD(5, 101) = ( 5 x 101 ) / 505

= 5 / 101

= 5

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 130, 685, 101, 455 is 1
