Given numbers are 455,172,240,472,326

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

The LCM of 455,172,240,472,326 is 9031517040.

Find LCM of 455,172,240,472,326 with Prime Factorization

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

2 x 2 x 2 x 5 x 91 x 43 x 6 x 59 x 163 = 9031517040

Therefore, the lowest common multiple of 455,172,240,472,326 is 9031517040.

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 172 x 240 x 472 x 326 = 2890085452800

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

172 : 1, 2, 4, 43, 86, 172

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

472 : 1, 2, 4, 8, 59, 118, 236, 472

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,172,240,472,326, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

172:2x 2x 43

240:2x 2x 2x 2x 3x 5

472:2x 2x 2x 59

326:2x 163

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 2x 2x 2x 5 = 320

Therefore, the value for common factors is 320.

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 = 2890085452800/(1x320)

LCM = 2890085452800/320

LCM = 9031517040

Thus, we can understand that the LCM of 455,172,240,472,326 is 9031517040.
