Given numbers are 806, 474, 985, 660

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 474 are 2 x 3 x 79

Prime factors of 985 are 5 x 197

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 806, 474, 985, 660

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

Apply this formula for all numbers.

Step1:

LCM(806, 474) = 191022

GCD(806, 474) = ( 806 x 474 ) / 191022

= 806 / 474

= 806

Step2:

LCM(2, 985) = 1970

GCD(2, 985) = ( 2 x 985 ) / 1970

= 2 / 985

= 2

Step3:

LCM(1, 660) = 660

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

= 1 / 660

= 1

So, Greatest Common Divisor of 806, 474, 985, 660 is 1
