Given numbers are 421,442,104,455,979

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

The LCM of 421,442,104,455,979 is 25504398920.

Find LCM of 421,442,104,455,979 with Prime Factorization

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

2 x 13 x 421 x 17 x 4 x 35 x 979 = 25504398920

Therefore, the lowest common multiple of 421,442,104,455,979 is 25504398920.

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.

421 x 442 x 104 x 455 x 979 = 8620486834960

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.

421 : 1, 421

442 : 1, 2, 13, 17, 26, 34, 221, 442

104 : 1, 2, 4, 8, 13, 26, 52, 104

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

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,442,104,455,979, is 1.

Now, the common factors can be found like this.

421:421

442:2x 13x 17

104:2x 2x 2x 13

455:5x 7x 13

979:11x 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 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 8620486834960/(1x338)

LCM = 8620486834960/338

LCM = 25504398920

Thus, we can understand that the LCM of 421,442,104,455,979 is 25504398920.
