Given numbers are 515, 283, 661, 804

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 283 are 283

Prime factors of 661 are 661

Prime factors of 804 are 2 x 2 x 3 x 67

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

Given numbers are 515, 283, 661, 804

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

Apply this formula for all numbers.

Step1:

LCM(515, 283) = 145745

GCD(515, 283) = ( 515 x 283 ) / 145745

= 515 / 283

= 515

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

= 1 / 804

= 1

So, Greatest Common Divisor of 515, 283, 661, 804 is 1
