Given numbers are 251,121,605,408

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

The LCM of 251,121,605,408 is 61956840.

Find LCM of 251,121,605,408 with Prime Factorization

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

11 x 11 x 251 x 1 x 5 x 408 = 61956840

Therefore, the lowest common multiple of 251,121,605,408 is 61956840.

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.

251 x 121 x 605 x 408 = 7496777640

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.

251 : 1, 251

121 : 1, 11, 121

605 : 1, 5, 11, 55, 121, 605

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,121,605,408, is 1.

Now, the common factors can be found like this.

251:251

121:11x 11

605:5x 11x 11

408:2x 2x 2x 3x 17

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 7496777640/(1x121)

LCM = 7496777640/121

LCM = 61956840

Thus, we can understand that the LCM of 251,121,605,408 is 61956840.
