Given numbers are 217,455,445,553

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

The LCM of 217,455,445,553 is 99172255.

Find LCM of 217,455,445,553 with Prime Factorization

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

5 x 7 x 31 x 13 x 89 x 79 = 99172255

Therefore, the lowest common multiple of 217,455,445,553 is 99172255.

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.

217 x 455 x 445 x 553 = 24297202475

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.

217 : 1, 7, 31, 217

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

445 : 1, 5, 89, 445

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,455,445,553, is 1.

Now, the common factors can be found like this.

217:7x 31

455:5x 7x 13

445:5x 89

553:7x 79

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

5x 7x 7 = 245

Therefore, the value for common factors is 245.

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 = 24297202475/(1x245)

LCM = 24297202475/245

LCM = 99172255

Thus, we can understand that the LCM of 217,455,445,553 is 99172255.
