Given numbers are 840,173,638,380,175

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

The LCM of 840,173,638,380,175 is 4403922600.

Find LCM of 840,173,638,380,175 with Prime Factorization

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

2 x 2 x 5 x 7 x 6 x 173 x 319 x 19 x 5 = 4403922600

Therefore, the lowest common multiple of 840,173,638,380,175 is 4403922600.

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.

840 x 173 x 638 x 380 x 175 = 6165491640000

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.

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

173 : 1, 173

638 : 1, 2, 11, 22, 29, 58, 319, 638

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

175 : 1, 5, 7, 25, 35, 175

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,173,638,380,175, is 1.

Now, the common factors can be found like this.

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

173:173

638:2x 11x 29

380:2x 2x 5x 19

175:5x 5x 7

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 5x 5x 7 = 1400

Therefore, the value for common factors is 1400.

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 = 6165491640000/(1x1400)

LCM = 6165491640000/1400

LCM = 4403922600

Thus, we can understand that the LCM of 840,173,638,380,175 is 4403922600.
