Given numbers are 51, 81, 72, 96

The list of prime factors of all numbers are

Prime factors of 51 are 3 x 17

Prime factors of 81 are 3 x 3 x 3 x 3

Prime factors of 72 are 2 x 2 x 2 x 3 x 3

Prime factors of 96 are 2 x 2 x 2 x 2 x 2 x 3

The highest common occurrence is 3¹

Therefore, GCD of 51, 81, 72, 96 is 3.

Given numbers are 51, 81, 72, 96

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

Apply this formula for all numbers.

Step1:

LCM(51, 81) = 1377

GCD(51, 81) = ( 51 x 81 ) / 1377

= 51 / 81

= 51

Step2:

LCM(3, 72) = 72

GCD(3, 72) = ( 3 x 72 ) / 72

= 3 / 72

= 3

Step3:

LCM(3, 96) = 96

GCD(3, 96) = ( 3 x 96 ) / 96

= 3 / 96

= 3

So, Greatest Common Divisor of 51, 81, 72, 96 is 3
