Given numbers are 477, 147, 570, 820

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 147 are 3 x 7 x 7

Prime factors of 570 are 2 x 3 x 5 x 19

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

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

Given numbers are 477, 147, 570, 820

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

Apply this formula for all numbers.

Step1:

LCM(477, 147) = 23373

GCD(477, 147) = ( 477 x 147 ) / 23373

= 477 / 147

= 477

Step2:

LCM(3, 570) = 570

GCD(3, 570) = ( 3 x 570 ) / 570

= 3 / 570

= 3

Step3:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

So, Greatest Common Divisor of 477, 147, 570, 820 is 1
