Given numbers are 411, 820, 205, 153

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

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

Prime factors of 205 are 5 x 41

Prime factors of 153 are 3 x 3 x 17

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

Given numbers are 411, 820, 205, 153

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

Apply this formula for all numbers.

Step1:

LCM(411, 820) = 337020

GCD(411, 820) = ( 411 x 820 ) / 337020

= 411 / 820

= 411

Step2:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

Step3:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

So, Greatest Common Divisor of 411, 820, 205, 153 is 1
