Given numbers are 867,221,860,765,944

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

The LCM of 867,221,860,765,944 is 6862686480.

Find LCM of 867,221,860,765,944 with Prime Factorization

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

2 x 2 x 3 x 5 x 17 x 17 x 13 x 43 x 3 x 236 = 6862686480

Therefore, the lowest common multiple of 867,221,860,765,944 is 6862686480.

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.

867 x 221 x 860 x 765 x 944 = 118998983563200

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.

867 : 1, 3, 17, 51, 289, 867

221 : 1, 13, 17, 221

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

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,221,860,765,944, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

221:13x 17

860:2x 2x 5x 43

765:3x 3x 5x 17

944:2x 2x 2x 2x 59

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 3x 5x 17x 17 = 17340

Therefore, the value for common factors is 17340.

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 = 118998983563200/(1x17340)

LCM = 118998983563200/17340

LCM = 6862686480

Thus, we can understand that the LCM of 867,221,860,765,944 is 6862686480.
