Given numbers are 828, 860, 772, 247

The list of prime factors of all numbers are

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 772 are 2 x 2 x 193

Prime factors of 247 are 13 x 19

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

Given numbers are 828, 860, 772, 247

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

Apply this formula for all numbers.

Step1:

LCM(828, 860) = 178020

GCD(828, 860) = ( 828 x 860 ) / 178020

= 828 / 860

= 828

Step2:

LCM(4, 772) = 772

GCD(4, 772) = ( 4 x 772 ) / 772

= 4 / 772

= 4

Step3:

LCM(4, 247) = 988

GCD(4, 247) = ( 4 x 247 ) / 988

= 4 / 247

= 4

So, Greatest Common Divisor of 828, 860, 772, 247 is 1
