Given numbers are 676,840,244,920

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

The LCM of 676,840,244,920 is 199169880.

Find LCM of 676,840,244,920 with Prime Factorization

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

2 x 2 x 2 x 5 x 169 x 21 x 61 x 23 = 199169880

Therefore, the lowest common multiple of 676,840,244,920 is 199169880.

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.

676 x 840 x 244 x 920 = 127468723200

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

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

244 : 1, 2, 4, 61, 122, 244

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,840,244,920, is 4.

Now, the common factors can be found like this.

676:2x 2x 13x 13

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

244:2x 2x 61

920:2x 2x 2x 5x 23

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 5 = 160

Therefore, the value for common factors is 160.

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 = 127468723200/(4x160)

LCM = 127468723200/640

LCM = 199169880

Thus, we can understand that the LCM of 676,840,244,920 is 199169880.
