Given numbers are 680, 506, 842, 993

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 506 are 2 x 11 x 23

Prime factors of 842 are 2 x 421

Prime factors of 993 are 3 x 331

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

Given numbers are 680, 506, 842, 993

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

Apply this formula for all numbers.

Step1:

LCM(680, 506) = 172040

GCD(680, 506) = ( 680 x 506 ) / 172040

= 680 / 506

= 680

Step2:

LCM(2, 842) = 842

GCD(2, 842) = ( 2 x 842 ) / 842

= 2 / 842

= 2

Step3:

LCM(2, 993) = 1986

GCD(2, 993) = ( 2 x 993 ) / 1986

= 2 / 993

= 2

So, Greatest Common Divisor of 680, 506, 842, 993 is 1
