Given numbers are 28,717,645

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

The LCM of 28,717,645 is 4316340.

Find LCM of 28,717,645 with Prime Factorization

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

3 x 28 x 239 x 215 = 4316340

Therefore, the lowest common multiple of 28,717,645 is 4316340.

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.

28 x 717 x 645 = 12949020

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.

28 : 1, 2, 4, 7, 14, 28

717 : 1, 3, 239, 717

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 28,717,645, is 1.

Now, the common factors can be found like this.

28:2x 2x 7

717:3x 239

645:3x 5x 43

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

3 = 3

Therefore, the value for common factors is 3.

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 = 12949020/(1x3)

LCM = 12949020/3

LCM = 4316340

Thus, we can understand that the LCM of 28,717,645 is 4316340.

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

• LCM of 23, 147, 499
• LCM of 62, 415, 889
