Given numbers are 805, 644, 662, 630

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 662 are 2 x 331

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 805, 644, 662, 630

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

Apply this formula for all numbers.

Step1:

LCM(805, 644) = 3220

GCD(805, 644) = ( 805 x 644 ) / 3220

= 805 / 644

= 805

Step2:

LCM(161, 662) = 106582

GCD(161, 662) = ( 161 x 662 ) / 106582

= 161 / 662

= 161

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 805, 644, 662, 630 is 1
