Given numbers are 455,393,898,890

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

The LCM of 455,393,898,890 is 14291252430.

Find LCM of 455,393,898,890 with Prime Factorization

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

2 x 5 x 91 x 393 x 449 x 89 = 14291252430

Therefore, the lowest common multiple of 455,393,898,890 is 14291252430.

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 393 x 898 x 890 = 142912524300

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

393 : 1, 3, 131, 393

898 : 1, 2, 449, 898

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,393,898,890, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

393:3x 131

898:2x 449

890:2x 5x 89

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 142912524300/(1x10)

LCM = 142912524300/10

LCM = 14291252430

Thus, we can understand that the LCM of 455,393,898,890 is 14291252430.
