Given numbers are 153, 981, 820, 444

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 981 are 3 x 3 x 109

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

Prime factors of 444 are 2 x 2 x 3 x 37

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

Given numbers are 153, 981, 820, 444

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

Apply this formula for all numbers.

Step1:

LCM(153, 981) = 16677

GCD(153, 981) = ( 153 x 981 ) / 16677

= 153 / 981

= 153

Step2:

LCM(9, 820) = 7380

GCD(9, 820) = ( 9 x 820 ) / 7380

= 9 / 820

= 9

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 153, 981, 820, 444 is 1
