To find the Least Common Multiple (L.C.M.) of the given numbers:

1. First number: $23 \times 32 \times 5 \times 11$
2. Second number: $24 \times 34 \times 52 \times 7$
3. Third number: $25 \times 33 \times 53 \times 72 \times 11$

The L.C.M. is found by taking the highest powers of all the prime factors involved.

Prime Factor Breakdown:

• Prime 2:

  • First number: $2^3$
  • Second number: $2^4$
  • Third number: $2^5$
  • Maximum power: $2^5$

• Prime 3:

  • First number: $3^2$
  • Second number: $3^4$
  • Third number: $3^3$
  • Maximum power: $3^4$

• Prime 5:

  • First number: $5$
  • Second number: $5^2$
  • Third number: $5^3$
  • Maximum power: $5^3$

• Prime 7:

  • First number: No 7
  • Second number: $7^1$
  • Third number: $7^2$
  • Maximum power: $7^2$

• Prime 11:

  • First number: $11^1$
  • Second number: No 11
  • Third number: $11^1$
  • Maximum power: $11^1$

L.C.M. is the product of the highest powers of all primes:

$\text{L.C.M.} = 2^5 \times 3^4 \times 5^3 \times 7^2 \times 11^1$

Now, let's calculate the L.C.M:

$2^5 = 32, \quad 3^4 = 81, \quad 5^3 = 125, \quad 7^2 = 49, \quad 11^1 = 11$

The L.C.M. is:

$32 \times 81 \times 125 \times 49 \times 11$

Let me calculate the exact value.The Least Common Multiple (L.C.M.) of the given numbers is $174,636,000$.
