Given numbers are 820, 492, 170, 147

The list of prime factors of all numbers are

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

Prime factors of 492 are 2 x 2 x 3 x 41

Prime factors of 170 are 2 x 5 x 17

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 820, 492, 170, 147

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

Apply this formula for all numbers.

Step1:

LCM(820, 492) = 2460

GCD(820, 492) = ( 820 x 492 ) / 2460

= 820 / 492

= 820

Step2:

LCM(164, 170) = 13940

GCD(164, 170) = ( 164 x 170 ) / 13940

= 164 / 170

= 164

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 820, 492, 170, 147 is 1
