Given numbers are 836, 213, 720, 220

The list of prime factors of all numbers are

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 213 are 3 x 71

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 836, 213, 720, 220

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

Apply this formula for all numbers.

Step1:

LCM(836, 213) = 178068

GCD(836, 213) = ( 836 x 213 ) / 178068

= 836 / 213

= 836

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 836, 213, 720, 220 is 1
