Given numbers are 636,860,668,224,620

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

The LCM of 636,860,668,224,620 is 39642566880.

Find LCM of 636,860,668,224,620 with Prime Factorization

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

2 x 2 x 5 x 159 x 43 x 167 x 56 x 31 = 39642566880

Therefore, the lowest common multiple of 636,860,668,224,620 is 39642566880.

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.

636 x 860 x 668 x 224 x 620 = 50742485606400

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

668 : 1, 2, 4, 167, 334, 668

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,860,668,224,620, is 4.

Now, the common factors can be found like this.

636:2x 2x 3x 53

860:2x 2x 5x 43

668:2x 2x 167

224:2x 2x 2x 2x 2x 7

620:2x 2x 5x 31

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 2x 2x 5 = 320

Therefore, the value for common factors is 320.

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 = 50742485606400/(4x320)

LCM = 50742485606400/1280

LCM = 39642566880

Thus, we can understand that the LCM of 636,860,668,224,620 is 39642566880.
