Given numbers are 720, 182, 642, 841

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 182 are 2 x 7 x 13

Prime factors of 642 are 2 x 3 x 107

Prime factors of 841 are 29 x 29

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

Given numbers are 720, 182, 642, 841

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

Apply this formula for all numbers.

Step1:

LCM(720, 182) = 65520

GCD(720, 182) = ( 720 x 182 ) / 65520

= 720 / 182

= 720

Step2:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

Step3:

LCM(2, 841) = 1682

GCD(2, 841) = ( 2 x 841 ) / 1682

= 2 / 841

= 2

So, Greatest Common Divisor of 720, 182, 642, 841 is 1
