Given numbers are 641,641,345

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

The LCM of 641,641,345 is 221145.

Find LCM of 641,641,345 with Prime Factorization

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

641 x 1 x 1 x 345 = 221145

Therefore, the lowest common multiple of 641,641,345 is 221145.

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.

641 x 641 x 345 = 141753945

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.

641 : 1, 641

641 : 1, 641

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,641,345, is 1.

Now, the common factors can be found like this.

641:641

641:641

345:3x 5x 23

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

641 = 641

Therefore, the value for common factors is 641.

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 = 141753945/(1x641)

LCM = 141753945/641

LCM = 221145

Thus, we can understand that the LCM of 641,641,345 is 221145.

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

• LCM of 659, 107, 397
• LCM of 377, 779, 672
