Given numbers are 807, 247, 220, 774

The list of prime factors of all numbers are

Prime factors of 807 are 3 x 269

Prime factors of 247 are 13 x 19

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 774 are 2 x 3 x 3 x 43

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

Given numbers are 807, 247, 220, 774

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

Apply this formula for all numbers.

Step1:

LCM(807, 247) = 199329

GCD(807, 247) = ( 807 x 247 ) / 199329

= 807 / 247

= 807

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 807, 247, 220, 774 is 1
