Given numbers are 520, 770, 866, 123

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Prime factors of 866 are 2 x 433

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 520, 770, 866, 123

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

Apply this formula for all numbers.

Step1:

LCM(520, 770) = 40040

GCD(520, 770) = ( 520 x 770 ) / 40040

= 520 / 770

= 520

Step2:

LCM(10, 866) = 4330

GCD(10, 866) = ( 10 x 866 ) / 4330

= 10 / 866

= 10

Step3:

LCM(2, 123) = 246

GCD(2, 123) = ( 2 x 123 ) / 246

= 2 / 123

= 2

So, Greatest Common Divisor of 520, 770, 866, 123 is 1
