how many factors in 10800

Solution

To find how many factors 1080010800 has, we first perform its prime factorization, then use the formula for determining the number of factors.

Step 1: Prime Factorization of 10800

We can start by factoring 1080010800:

10800÷2=540010800 \div 2 = 5400 5400÷2=27005400 \div 2 = 2700 2700÷2=13502700 \div 2 = 1350 1350÷2=675(675 is not divisible by 2)1350 \div 2 = 675 \quad (\text{675 is not divisible by } 2) 675÷3=225675 \div 3 = 225 225÷3=75225 \div 3 = 75 75÷3=2575 \div 3 = 25 25÷5=525 \div 5 = 5 5÷5=15 \div 5 = 1

Thus, 10800=24×33×5210800 = 2^4 \times 3^3 \times 5^2.

Step 2: Finding the Number of Factors

The formula for determining the number of factors of a number from its prime factorization is:

Number of factors=(e1+1)(e2+1)(e3+1)\text{Number of factors} = (e_1 + 1)(e_2 + 1)(e_3 + 1) \cdots where e1,e2,e3,e_1, e_2, e_3, \dots are the exponents of the prime factors.

For 10800=24×33×5210800 = 2^4 \times 3^3 \times 5^2, the exponents are 4, 3, and 2. So:

Number of factors=(4+1)(3+1)(2+1)=5×4×3=60\text{Number of factors} = (4+1)(3+1)(2+1) = 5 \times 4 \times 3 = 60

Conclusion:

The number of factors of 1080010800 is 60.
