Given numbers are 670, 205, 185, 721

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 205 are 5 x 41

Prime factors of 185 are 5 x 37

Prime factors of 721 are 7 x 103

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

Given numbers are 670, 205, 185, 721

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

Apply this formula for all numbers.

Step1:

LCM(670, 205) = 27470

GCD(670, 205) = ( 670 x 205 ) / 27470

= 670 / 205

= 670

Step2:

LCM(5, 185) = 185

GCD(5, 185) = ( 5 x 185 ) / 185

= 5 / 185

= 5

Step3:

LCM(5, 721) = 3605

GCD(5, 721) = ( 5 x 721 ) / 3605

= 5 / 721

= 5

So, Greatest Common Divisor of 670, 205, 185, 721 is 1
