Given numbers are 515, 661, 770, 824

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 661 are 661

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 824 are 2 x 2 x 2 x 103

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

Given numbers are 515, 661, 770, 824

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

Apply this formula for all numbers.

Step1:

LCM(515, 661) = 340415

GCD(515, 661) = ( 515 x 661 ) / 340415

= 515 / 661

= 515

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 824) = 824

GCD(1, 824) = ( 1 x 824 ) / 824

= 1 / 824

= 1

So, Greatest Common Divisor of 515, 661, 770, 824 is 1
