Given numbers are 720, 155, 163, 746

The list of prime factors of all numbers are

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

Prime factors of 155 are 5 x 31

Prime factors of 163 are 163

Prime factors of 746 are 2 x 373

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

Given numbers are 720, 155, 163, 746

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

Apply this formula for all numbers.

Step1:

LCM(720, 155) = 22320

GCD(720, 155) = ( 720 x 155 ) / 22320

= 720 / 155

= 720

Step2:

LCM(5, 163) = 815

GCD(5, 163) = ( 5 x 163 ) / 815

= 5 / 163

= 5

Step3:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

So, Greatest Common Divisor of 720, 155, 163, 746 is 1
