Given numbers are 121,225,449,885,970

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

The LCM of 121,225,449,885,970 is 139916190150.

Find LCM of 121,225,449,885,970 with Prime Factorization

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

3 x 5 x 121 x 15 x 449 x 59 x 194 = 139916190150

Therefore, the lowest common multiple of 121,225,449,885,970 is 139916190150.

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 225 x 449 x 885 x 970 = 10493714261250

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

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

449 : 1, 449

885 : 1, 3, 5, 15, 59, 177, 295, 885

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,225,449,885,970, is 1.

Now, the common factors can be found like this.

121:11x 11

225:3x 3x 5x 5

449:449

885:3x 5x 59

970:2x 5x 97

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 10493714261250/(1x75)

LCM = 10493714261250/75

LCM = 139916190150

Thus, we can understand that the LCM of 121,225,449,885,970 is 139916190150.
