Given numbers are 643,206,253,299

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

The LCM of 643,206,253,299 is 435654362.

Find LCM of 643,206,253,299 with Prime Factorization

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

23 x 643 x 206 x 11 x 13 = 435654362

Therefore, the lowest common multiple of 643,206,253,299 is 435654362.

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 206 x 253 x 299 = 10020050326

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

206 : 1, 2, 103, 206

253 : 1, 11, 23, 253

299 : 1, 13, 23, 299

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,206,253,299, is 1.

Now, the common factors can be found like this.

643:643

206:2x 103

253:11x 23

299:13x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 10020050326/(1x23)

LCM = 10020050326/23

LCM = 435654362

Thus, we can understand that the LCM of 643,206,253,299 is 435654362.
