Given numbers are 782, 820, 685, 167

The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 685 are 5 x 137

Prime factors of 167 are 167

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

Given numbers are 782, 820, 685, 167

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

Apply this formula for all numbers.

Step1:

LCM(782, 820) = 320620

GCD(782, 820) = ( 782 x 820 ) / 320620

= 782 / 820

= 782

Step2:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

Step3:

LCM(1, 167) = 167

GCD(1, 167) = ( 1 x 167 ) / 167

= 1 / 167

= 1

So, Greatest Common Divisor of 782, 820, 685, 167 is 1
