Given numbers are 121,407,442,874

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

The LCM of 121,407,442,874 is 864750458.

Find LCM of 121,407,442,874 with Prime Factorization

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

2 x 11 x 11 x 37 x 221 x 437 = 864750458

Therefore, the lowest common multiple of 121,407,442,874 is 864750458.

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.

121 x 407 x 442 x 874 = 19024510076

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.

121 : 1, 11, 121

407 : 1, 11, 37, 407

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

874 : 1, 2, 19, 23, 38, 46, 437, 874

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,407,442,874, is 1.

Now, the common factors can be found like this.

121:11x 11

407:11x 37

442:2x 13x 17

874:2x 19x 23

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 19024510076/(1x22)

LCM = 19024510076/22

LCM = 864750458

Thus, we can understand that the LCM of 121,407,442,874 is 864750458.
