Given numbers are 842, 993, 945, 664

The list of prime factors of all numbers are

Prime factors of 842 are 2 x 421

Prime factors of 993 are 3 x 331

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 842, 993, 945, 664

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

Apply this formula for all numbers.

Step1:

LCM(842, 993) = 836106

GCD(842, 993) = ( 842 x 993 ) / 836106

= 842 / 993

= 842

Step2:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 842, 993, 945, 664 is 1
