Given numbers are 674,447,520

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

The LCM of 674,447,520 is 78332280.

Find LCM of 674,447,520 with Prime Factorization

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

2 x 337 x 447 x 260 = 78332280

Therefore, the lowest common multiple of 674,447,520 is 78332280.

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.

674 x 447 x 520 = 156664560

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.

674 : 1, 2, 337, 674

447 : 1, 3, 149, 447

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,447,520, is 1.

Now, the common factors can be found like this.

674:2x 337

447:3x 149

520:2x 2x 2x 5x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 156664560/(1x2)

LCM = 156664560/2

LCM = 78332280

Thus, we can understand that the LCM of 674,447,520 is 78332280.
