Given numbers are 121,974,886,818,409

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

The LCM of 121,974,886,818,409 is 21353612698.

Find LCM of 121,974,886,818,409 with Prime Factorization

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

2 x 409 x 121 x 487 x 443 x 1 x 1 = 21353612698

Therefore, the lowest common multiple of 121,974,886,818,409 is 21353612698.

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 974 x 886 x 818 x 409 = 34934510373928

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

974 : 1, 2, 487, 974

886 : 1, 2, 443, 886

818 : 1, 2, 409, 818

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,974,886,818,409, is 1.

Now, the common factors can be found like this.

121:11x 11

974:2x 487

886:2x 443

818:2x 409

409:409

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

2x 2x 409 = 1636

Therefore, the value for common factors is 1636.

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 = 34934510373928/(1x1636)

LCM = 34934510373928/1636

LCM = 21353612698

Thus, we can understand that the LCM of 121,974,886,818,409 is 21353612698.
