Given numbers are 155, 792, 858, 720

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 858 are 2 x 3 x 11 x 13

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 155, 792, 858, 720

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

Apply this formula for all numbers.

Step1:

LCM(155, 792) = 122760

GCD(155, 792) = ( 155 x 792 ) / 122760

= 155 / 792

= 155

Step2:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 155, 792, 858, 720 is 1
