Given numbers are 721, 558, 880, 142

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 142 are 2 x 71

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

Given numbers are 721, 558, 880, 142

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

Apply this formula for all numbers.

Step1:

LCM(721, 558) = 402318

GCD(721, 558) = ( 721 x 558 ) / 402318

= 721 / 558

= 721

Step2:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 721, 558, 880, 142 is 1
