Given numbers are 644,240,630,893,330

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

The LCM of 644,240,630,893,330 is 1138682160.

Find LCM of 644,240,630,893,330 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 23 x 4 x 3 x 893 x 11 = 1138682160

Therefore, the lowest common multiple of 644,240,630,893,330 is 1138682160.

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.

644 x 240 x 630 x 893 x 330 = 28694790432000

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

893 : 1, 19, 47, 893

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,240,630,893,330, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

240:2x 2x 2x 2x 3x 5

630:2x 3x 3x 5x 7

893:19x 47

330:2x 3x 5x 11

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

2x 2x 2x 2x 3x 3x 5x 5x 7 = 25200

Therefore, the value for common factors is 25200.

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 = 28694790432000/(1x25200)

LCM = 28694790432000/25200

LCM = 1138682160

Thus, we can understand that the LCM of 644,240,630,893,330 is 1138682160.
