Given numbers are 253, 780, 814, 851

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

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

Prime factors of 814 are 2 x 11 x 37

Prime factors of 851 are 23 x 37

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

Given numbers are 253, 780, 814, 851

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

Apply this formula for all numbers.

Step1:

LCM(253, 780) = 197340

GCD(253, 780) = ( 253 x 780 ) / 197340

= 253 / 780

= 253

Step2:

LCM(1, 814) = 814

GCD(1, 814) = ( 1 x 814 ) / 814

= 1 / 814

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 253, 780, 814, 851 is 1
