Given numbers are 556, 417, 562, 820

The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 417 are 3 x 139

Prime factors of 562 are 2 x 281

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 556, 417, 562, 820

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

Apply this formula for all numbers.

Step1:

LCM(556, 417) = 1668

GCD(556, 417) = ( 556 x 417 ) / 1668

= 556 / 417

= 556

Step2:

LCM(139, 562) = 78118

GCD(139, 562) = ( 139 x 562 ) / 78118

= 139 / 562

= 139

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 556, 417, 562, 820 is 1
