Given numbers are 859, 761, 345, 720

The list of prime factors of all numbers are

Prime factors of 859 are 859

Prime factors of 761 are 761

Prime factors of 345 are 3 x 5 x 23

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 859, 761, 345, 720

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

Apply this formula for all numbers.

Step1:

LCM(859, 761) = 653699

GCD(859, 761) = ( 859 x 761 ) / 653699

= 859 / 761

= 859

Step2:

LCM(1, 345) = 345

GCD(1, 345) = ( 1 x 345 ) / 345

= 1 / 345

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 859, 761, 345, 720 is 1
