Given numbers are 407, 620, 115, 254

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 115 are 5 x 23

Prime factors of 254 are 2 x 127

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

Given numbers are 407, 620, 115, 254

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

Apply this formula for all numbers.

Step1:

LCM(407, 620) = 252340

GCD(407, 620) = ( 407 x 620 ) / 252340

= 407 / 620

= 407

Step2:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 407, 620, 115, 254 is 1
