Given numbers are 670, 805, 180, 621

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 805 are 5 x 7 x 23

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 670, 805, 180, 621

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

Apply this formula for all numbers.

Step1:

LCM(670, 805) = 107870

GCD(670, 805) = ( 670 x 805 ) / 107870

= 670 / 805

= 670

Step2:

LCM(5, 180) = 180

GCD(5, 180) = ( 5 x 180 ) / 180

= 5 / 180

= 5

Step3:

LCM(5, 621) = 3105

GCD(5, 621) = ( 5 x 621 ) / 3105

= 5 / 621

= 5

So, Greatest Common Divisor of 670, 805, 180, 621 is 1
