Given numbers are 861, 462, 506, 212

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 506 are 2 x 11 x 23

Prime factors of 212 are 2 x 2 x 53

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

Given numbers are 861, 462, 506, 212

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

Apply this formula for all numbers.

Step1:

LCM(861, 462) = 18942

GCD(861, 462) = ( 861 x 462 ) / 18942

= 861 / 462

= 861

Step2:

LCM(21, 506) = 10626

GCD(21, 506) = ( 21 x 506 ) / 10626

= 21 / 506

= 21

Step3:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 861, 462, 506, 212 is 1
