Given numbers are 145, 615, 415, 287

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 615 are 3 x 5 x 41

Prime factors of 415 are 5 x 83

Prime factors of 287 are 7 x 41

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

Given numbers are 145, 615, 415, 287

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

Apply this formula for all numbers.

Step1:

LCM(145, 615) = 17835

GCD(145, 615) = ( 145 x 615 ) / 17835

= 145 / 615

= 145

Step2:

LCM(5, 415) = 415

GCD(5, 415) = ( 5 x 415 ) / 415

= 5 / 415

= 5

Step3:

LCM(5, 287) = 1435

GCD(5, 287) = ( 5 x 287 ) / 1435

= 5 / 287

= 5

So, Greatest Common Divisor of 145, 615, 415, 287 is 1
