Given numbers are 745,447,392,547

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

The LCM of 745,447,392,547 is 479237640.

Find LCM of 745,447,392,547 with Prime Factorization

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

149 x 5 x 3 x 392 x 547 = 479237640

Therefore, the lowest common multiple of 745,447,392,547 is 479237640.

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.

745 x 447 x 392 x 547 = 71406408360

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.

745 : 1, 5, 149, 745

447 : 1, 3, 149, 447

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,447,392,547, is 1.

Now, the common factors can be found like this.

745:5x 149

447:3x 149

392:2x 2x 2x 7x 7

547:547

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

149 = 149

Therefore, the value for common factors is 149.

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 = 71406408360/(1x149)

LCM = 71406408360/149

LCM = 479237640

Thus, we can understand that the LCM of 745,447,392,547 is 479237640.
