Given numbers are 643,225,423,277

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

The LCM of 643,225,423,277 is 1883523825.

Find LCM of 643,225,423,277 with Prime Factorization

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

3 x 3 x 643 x 25 x 47 x 277 = 1883523825

Therefore, the lowest common multiple of 643,225,423,277 is 1883523825.

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.

643 x 225 x 423 x 277 = 16951714425

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.

643 : 1, 643

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

423 : 1, 3, 9, 47, 141, 423

277 : 1, 277

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,225,423,277, is 1.

Now, the common factors can be found like this.

643:643

225:3x 3x 5x 5

423:3x 3x 47

277:277

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 16951714425/(1x9)

LCM = 16951714425/9

LCM = 1883523825

Thus, we can understand that the LCM of 643,225,423,277 is 1883523825.
