Given numbers are 146,860,803,390,820

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

The LCM of 146,860,803,390,820 is 1104237420.

Find LCM of 146,860,803,390,820 with Prime Factorization

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

2 x 2 x 5 x 73 x 1 x 43 x 11 x 39 x 41 = 1104237420

Therefore, the lowest common multiple of 146,860,803,390,820 is 1104237420.

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.

146 x 860 x 803 x 390 x 820 = 32243732664000

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.

146 : 1, 2, 73, 146

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

803 : 1, 11, 73, 803

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,860,803,390,820, is 1.

Now, the common factors can be found like this.

146:2x 73

860:2x 2x 5x 43

803:11x 73

390:2x 3x 5x 13

820:2x 2x 5x 41

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 5x 5x 73 = 29200

Therefore, the value for common factors is 29200.

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 = 32243732664000/(1x29200)

LCM = 32243732664000/29200

LCM = 1104237420

Thus, we can understand that the LCM of 146,860,803,390,820 is 1104237420.
