Given numbers are 820, 470, 122, 435

The list of prime factors of all numbers are

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

Prime factors of 470 are 2 x 5 x 47

Prime factors of 122 are 2 x 61

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 820, 470, 122, 435

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

Apply this formula for all numbers.

Step1:

LCM(820, 470) = 38540

GCD(820, 470) = ( 820 x 470 ) / 38540

= 820 / 470

= 820

Step2:

LCM(10, 122) = 610

GCD(10, 122) = ( 10 x 122 ) / 610

= 10 / 122

= 10

Step3:

LCM(2, 435) = 870

GCD(2, 435) = ( 2 x 435 ) / 870

= 2 / 435

= 2

So, Greatest Common Divisor of 820, 470, 122, 435 is 1
