Given numbers are 873, 765, 620, 402

The list of prime factors of all numbers are

Prime factors of 873 are 3 x 3 x 97

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 873, 765, 620, 402

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

Apply this formula for all numbers.

Step1:

LCM(873, 765) = 74205

GCD(873, 765) = ( 873 x 765 ) / 74205

= 873 / 765

= 873

Step2:

LCM(9, 620) = 5580

GCD(9, 620) = ( 9 x 620 ) / 5580

= 9 / 620

= 9

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 873, 765, 620, 402 is 1
