Given numbers are 815, 806, 660, 524

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 806 are 2 x 13 x 31

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

Prime factors of 524 are 2 x 2 x 131

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

Given numbers are 815, 806, 660, 524

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

Apply this formula for all numbers.

Step1:

LCM(815, 806) = 656890

GCD(815, 806) = ( 815 x 806 ) / 656890

= 815 / 806

= 815

Step2:

LCM(1, 660) = 660

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

= 1 / 660

= 1

Step3:

LCM(1, 524) = 524

GCD(1, 524) = ( 1 x 524 ) / 524

= 1 / 524

= 1

So, Greatest Common Divisor of 815, 806, 660, 524 is 1
