The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 515 are 5 x 103

Prime factors of 278 are 2 x 139

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 822, 515, 278, 772

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

Apply this formula for all numbers.

Step1:

LCM(822, 515) = 423330

GCD(822, 515) = ( 822 x 515 ) / 423330

= 822 / 515

= 822

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 822, 515, 278, 772 is 1
