Given numbers are 351,404,421,455

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

The LCM of 351,404,421,455 is 2089481940.

Find LCM of 351,404,421,455 with Prime Factorization

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

13 x 27 x 404 x 421 x 35 = 2089481940

Therefore, the lowest common multiple of 351,404,421,455 is 2089481940.

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.

351 x 404 x 421 x 455 = 27163265220

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

404 : 1, 2, 4, 101, 202, 404

421 : 1, 421

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,404,421,455, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

404:2x 2x 101

421:421

455:5x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 27163265220/(1x13)

LCM = 27163265220/13

LCM = 2089481940

Thus, we can understand that the LCM of 351,404,421,455 is 2089481940.
