Given numbers are 162, 620, 787, 860

The list of prime factors of all numbers are

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Prime factors of 787 are 787

Prime factors of 860 are 2 x 2 x 5 x 43

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

Given numbers are 162, 620, 787, 860

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

Apply this formula for all numbers.

Step1:

LCM(162, 620) = 50220

GCD(162, 620) = ( 162 x 620 ) / 50220

= 162 / 620

= 162

Step2:

LCM(2, 787) = 1574

GCD(2, 787) = ( 2 x 787 ) / 1574

= 2 / 787

= 2

Step3:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

So, Greatest Common Divisor of 162, 620, 787, 860 is 1
