Given numbers are 301, 245, 137, 455

The list of prime factors of all numbers are

Prime factors of 301 are 7 x 43

Prime factors of 245 are 5 x 7 x 7

Prime factors of 137 are 137

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 301, 245, 137, 455

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

Apply this formula for all numbers.

Step1:

LCM(301, 245) = 10535

GCD(301, 245) = ( 301 x 245 ) / 10535

= 301 / 245

= 301

Step2:

LCM(7, 137) = 959

GCD(7, 137) = ( 7 x 137 ) / 959

= 7 / 137

= 7

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 301, 245, 137, 455 is 1
