Given numbers are 802, 855, 780, 530

The list of prime factors of all numbers are

Prime factors of 802 are 2 x 401

Prime factors of 855 are 3 x 3 x 5 x 19

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

Prime factors of 530 are 2 x 5 x 53

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

Given numbers are 802, 855, 780, 530

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

Apply this formula for all numbers.

Step1:

LCM(802, 855) = 685710

GCD(802, 855) = ( 802 x 855 ) / 685710

= 802 / 855

= 802

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 802, 855, 780, 530 is 1
