Given numbers are 670,305,791,840,469

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

The LCM of 670,305,791,840,469 is 387938040.

Find LCM of 670,305,791,840,469 with Prime Factorization

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

2 x 5 x 7 x 67 x 1 x 61 x 113 x 12 x 1 = 387938040

Therefore, the lowest common multiple of 670,305,791,840,469 is 387938040.

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.

670 x 305 x 791 x 840 x 469 = 63680029266000

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

305 : 1, 5, 61, 305

791 : 1, 7, 113, 791

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

469 : 1, 7, 67, 469

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,305,791,840,469, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

305:5x 61

791:7x 113

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

469:7x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 5x 7x 7x 67 = 164150

Therefore, the value for common factors is 164150.

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 = 63680029266000/(1x164150)

LCM = 63680029266000/164150

LCM = 387938040

Thus, we can understand that the LCM of 670,305,791,840,469 is 387938040.
