Given numbers are 845, 209, 513, 660

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 209 are 11 x 19

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 845, 209, 513, 660

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

Apply this formula for all numbers.

Step1:

LCM(845, 209) = 176605

GCD(845, 209) = ( 845 x 209 ) / 176605

= 845 / 209

= 845

Step2:

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

= 1 / 513

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 845, 209, 513, 660 is 1
