Given numbers are 247, 762, 770, 123

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 762 are 2 x 3 x 127

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 123 are 3 x 41

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

Given numbers are 247, 762, 770, 123

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

Apply this formula for all numbers.

Step1:

LCM(247, 762) = 188214

GCD(247, 762) = ( 247 x 762 ) / 188214

= 247 / 762

= 247

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 247, 762, 770, 123 is 1
