Given numbers are 981, 576, 871, 215

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 871 are 13 x 67

Prime factors of 215 are 5 x 43

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

Given numbers are 981, 576, 871, 215

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

Apply this formula for all numbers.

Step1:

LCM(981, 576) = 62784

GCD(981, 576) = ( 981 x 576 ) / 62784

= 981 / 576

= 981

Step2:

LCM(9, 871) = 7839

GCD(9, 871) = ( 9 x 871 ) / 7839

= 9 / 871

= 9

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 981, 576, 871, 215 is 1
