Given numbers are 842, 718, 681, 840

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 718 are 2 x 359

Prime factors of 681 are 3 x 227

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 842, 718, 681, 840

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

Apply this formula for all numbers.

Step1:

LCM(842, 718) = 302278

GCD(842, 718) = ( 842 x 718 ) / 302278

= 842 / 718

= 842

Step2:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 842, 718, 681, 840 is 1
