Given numbers are 670, 561, 345, 916

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 561 are 3 x 11 x 17

Prime factors of 345 are 3 x 5 x 23

Prime factors of 916 are 2 x 2 x 229

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

Given numbers are 670, 561, 345, 916

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

Apply this formula for all numbers.

Step1:

LCM(670, 561) = 375870

GCD(670, 561) = ( 670 x 561 ) / 375870

= 670 / 561

= 670

Step2:

LCM(1, 345) = 345

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

= 1 / 345

= 1

Step3:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

So, Greatest Common Divisor of 670, 561, 345, 916 is 1
