Given numbers are 720, 175, 988, 161

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 175 are 5 x 5 x 7

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 161 are 7 x 23

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

Given numbers are 720, 175, 988, 161

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

Apply this formula for all numbers.

Step1:

LCM(720, 175) = 25200

GCD(720, 175) = ( 720 x 175 ) / 25200

= 720 / 175

= 720

Step2:

LCM(5, 988) = 4940

GCD(5, 988) = ( 5 x 988 ) / 4940

= 5 / 988

= 5

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 720, 175, 988, 161 is 1
