Given numbers are 860,173,210,972,520

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

The LCM of 860,173,210,972,520 is 6579944280.

Find LCM of 860,173,210,972,520 with Prime Factorization

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

2 x 2 x 3 x 5 x 43 x 173 x 7 x 81 x 26 = 6579944280

Therefore, the lowest common multiple of 860,173,210,972,520 is 6579944280.

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.

860 x 173 x 210 x 972 x 520 = 15791866272000

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.

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

173 : 1, 173

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,173,210,972,520, is 1.

Now, the common factors can be found like this.

860:2x 2x 5x 43

173:173

210:2x 3x 5x 7

972:2x 2x 3x 3x 3x 3x 3

520:2x 2x 2x 5x 13

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 3x 5x 5 = 2400

Therefore, the value for common factors is 2400.

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 = 15791866272000/(1x2400)

LCM = 15791866272000/2400

LCM = 6579944280

Thus, we can understand that the LCM of 860,173,210,972,520 is 6579944280.
