Find the LCM of 9,25,36 and 73 ?

The least common multiple is 65700

Step-by-step explanation:

To begin, find the prime factors of the given numbers, (and you find they have very little in common.)

9=3×3   25=5×5   36=2×2×3×3  73= 73×1  (73 is a prime number)

Only the 3's of 36 overlap with the 3's of 9

To find the LCM you must multiply all the prime factors that don't overlap:

3×3×5×5×2×2×73

If the 73 is changed to 72, the LCM is a somewhat lower number: 1800.

To test these LCM's try dividing by any of the factors or numbers given.

If the quotient is not a whole number, the LCM doesn't include that factor.

the correct answer is d
