Given numbers are 842, 690, 394, 693

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 394 are 2 x 197

Prime factors of 693 are 3 x 3 x 7 x 11

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

Given numbers are 842, 690, 394, 693

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

Apply this formula for all numbers.

Step1:

LCM(842, 690) = 290490

GCD(842, 690) = ( 842 x 690 ) / 290490

= 842 / 690

= 842

Step2:

LCM(2, 394) = 394

GCD(2, 394) = ( 2 x 394 ) / 394

= 2 / 394

= 2

Step3:

LCM(2, 693) = 1386

GCD(2, 693) = ( 2 x 693 ) / 1386

= 2 / 693

= 2

So, Greatest Common Divisor of 842, 690, 394, 693 is 1
