Given numbers are 118, 131, 648, 720

The list of prime factors of all numbers are

Prime factors of 118 are 2 x 59

Prime factors of 131 are 131

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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 118, 131, 648, 720

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

Apply this formula for all numbers.

Step1:

LCM(118, 131) = 15458

GCD(118, 131) = ( 118 x 131 ) / 15458

= 118 / 131

= 118

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 118, 131, 648, 720 is 1
