Given numbers are 777, 810, 842, 545

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 842 are 2 x 421

Prime factors of 545 are 5 x 109

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

Given numbers are 777, 810, 842, 545

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

Apply this formula for all numbers.

Step1:

LCM(777, 810) = 209790

GCD(777, 810) = ( 777 x 810 ) / 209790

= 777 / 810

= 777

Step2:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 777, 810, 842, 545 is 1
