Given numbers are 455,153,272,605,670

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

The LCM of 455,153,272,605,670 is 9029900880.

Find LCM of 455,153,272,605,670 with Prime Factorization

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

2 x 5 x 17 x 91 x 9 x 8 x 121 x 67 = 9029900880

Therefore, the lowest common multiple of 455,153,272,605,670 is 9029900880.

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.

455 x 153 x 272 x 605 x 670 = 7675415748000

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

153 : 1, 3, 9, 17, 51, 153

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

605 : 1, 5, 11, 55, 121, 605

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,153,272,605,670, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

153:3x 3x 17

272:2x 2x 2x 2x 17

605:5x 11x 11

670:2x 5x 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 17 = 850

Therefore, the value for common factors is 850.

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 = 7675415748000/(1x850)

LCM = 7675415748000/850

LCM = 9029900880

Thus, we can understand that the LCM of 455,153,272,605,670 is 9029900880.
