Given numbers are 643,199,643

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

The LCM of 643,199,643 is 127957.

Find LCM of 643,199,643 with Prime Factorization

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

643 x 1 x 199 x 1 = 127957

Therefore, the lowest common multiple of 643,199,643 is 127957.

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 199 x 643 = 82276351

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

199 : 1, 199

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,199,643, is 1.

Now, the common factors can be found like this.

643:643

199:199

643:643

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

643 = 643

Therefore, the value for common factors is 643.

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 = 82276351/(1x643)

LCM = 82276351/643

LCM = 127957

Thus, we can understand that the LCM of 643,199,643 is 127957.

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

• LCM of 887, 162, 596
• LCM of 650, 791, 297
