Given numbers are 947,890,445

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 947,890,445 is 842830.

Find LCM of 947,890,445 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

5 x 89 x 947 x 2 x 1 = 842830

Therefore, the lowest common multiple of 947,890,445 is 842830.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

947 x 890 x 445 = 375059350

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

947 : 1, 947

890 : 1, 2, 5, 10, 89, 178, 445, 890

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,890,445, is 1.

Now, the common factors can be found like this.

947:947

890:2x 5x 89

445:5x 89

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 89 = 445

Therefore, the value for common factors is 445.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 375059350/(1x445)

LCM = 375059350/445

LCM = 842830

Thus, we can understand that the LCM of 947,890,445 is 842830.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 261, 200, 623
• LCM of 231, 462, 159
