Given numbers are 415, 312, 345, 653

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 345 are 3 x 5 x 23

Prime factors of 653 are 653

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

Given numbers are 415, 312, 345, 653

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

Apply this formula for all numbers.

Step1:

LCM(415, 312) = 129480

GCD(415, 312) = ( 415 x 312 ) / 129480

= 415 / 312

= 415

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 415, 312, 345, 653 is 1
