Given numbers are 669, 131, 720, 138

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

Prime factors of 131 are 131

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

Prime factors of 138 are 2 x 3 x 23

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

Given numbers are 669, 131, 720, 138

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

Apply this formula for all numbers.

Step1:

LCM(669, 131) = 87639

GCD(669, 131) = ( 669 x 131 ) / 87639

= 669 / 131

= 669

Step2:

LCM(1, 720) = 720

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

= 1 / 720

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 669, 131, 720, 138 is 1
