Given numbers are 916,840,834,221

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

The LCM of 916,840,834,221 is 5909106840.

Find LCM of 916,840,834,221 with Prime Factorization

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

2 x 2 x 3 x 229 x 70 x 139 x 221 = 5909106840

Therefore, the lowest common multiple of 916,840,834,221 is 5909106840.

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.

916 x 840 x 834 x 221 = 141818564160

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.

916 : 1, 2, 4, 229, 458, 916

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

834 : 1, 2, 3, 6, 139, 278, 417, 834

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,840,834,221, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

840:2x 2x 2x 3x 5x 7

834:2x 3x 139

221:13x 17

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 3 = 24

Therefore, the value for common factors is 24.

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 = 141818564160/(1x24)

LCM = 141818564160/24

LCM = 5909106840

Thus, we can understand that the LCM of 916,840,834,221 is 5909106840.
