The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 247 are 13 x 19

Prime factors of 715 are 5 x 11 x 13

Prime factors of 301 are 7 x 43

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

Given numbers are 155, 247, 715, 301

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

Apply this formula for all numbers.

Step1:

LCM(155, 247) = 38285

GCD(155, 247) = ( 155 x 247 ) / 38285

= 155 / 247

= 155

Step2:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

Step3:

LCM(1, 301) = 301

GCD(1, 301) = ( 1 x 301 ) / 301

= 1 / 301

= 1

So, Greatest Common Divisor of 155, 247, 715, 301 is 1
