Given numbers are 820, 425, 441, 783

The list of prime factors of all numbers are

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

Prime factors of 425 are 5 x 5 x 17

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 820, 425, 441, 783

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

Apply this formula for all numbers.

Step1:

LCM(820, 425) = 69700

GCD(820, 425) = ( 820 x 425 ) / 69700

= 820 / 425

= 820

Step2:

LCM(5, 441) = 2205

GCD(5, 441) = ( 5 x 441 ) / 2205

= 5 / 441

= 5

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 820, 425, 441, 783 is 1
