Given numbers are 845, 565, 392, 660

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 565 are 5 x 113

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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, 565, 392, 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, 565) = 95485

GCD(845, 565) = ( 845 x 565 ) / 95485

= 845 / 565

= 845

Step2:

LCM(5, 392) = 1960

GCD(5, 392) = ( 5 x 392 ) / 1960

= 5 / 392

= 5

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 845, 565, 392, 660 is 1
