Given numbers are 820, 144, 47, 666

The list of prime factors of all numbers are

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

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 47 are 47

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 820, 144, 47, 666

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

Apply this formula for all numbers.

Step1:

LCM(820, 144) = 29520

GCD(820, 144) = ( 820 x 144 ) / 29520

= 820 / 144

= 820

Step2:

LCM(4, 47) = 188

GCD(4, 47) = ( 4 x 47 ) / 188

= 4 / 47

= 4

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 820, 144, 47, 666 is 1
