Given numbers are 415, 370, 351, 561

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 370 are 2 x 5 x 37

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 415, 370, 351, 561

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

Apply this formula for all numbers.

Step1:

LCM(415, 370) = 30710

GCD(415, 370) = ( 415 x 370 ) / 30710

= 415 / 370

= 415

Step2:

LCM(5, 351) = 1755

GCD(5, 351) = ( 5 x 351 ) / 1755

= 5 / 351

= 5

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 415, 370, 351, 561 is 1
