Given numbers are 780, 550, 852, 515

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 515 are 5 x 103

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

Given numbers are 780, 550, 852, 515

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

Apply this formula for all numbers.

Step1:

LCM(780, 550) = 42900

GCD(780, 550) = ( 780 x 550 ) / 42900

= 780 / 550

= 780

Step2:

LCM(10, 852) = 4260

GCD(10, 852) = ( 10 x 852 ) / 4260

= 10 / 852

= 10

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 780, 550, 852, 515 is 1
