Given numbers are 121,416,855,260,276

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

The LCM of 121,416,855,260,276 is 989857440.

Find LCM of 121,416,855,260,276 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 121 x 8 x 57 x 1 x 23 = 989857440

Therefore, the lowest common multiple of 121,416,855,260,276 is 989857440.

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 416 x 855 x 260 x 276 = 3088355212800

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

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,416,855,260,276, is 1.

Now, the common factors can be found like this.

121:11x 11

416:2x 2x 2x 2x 2x 13

855:3x 3x 5x 19

260:2x 2x 5x 13

276:2x 2x 3x 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 2x 2x 2x 3x 5x 13 = 3120

Therefore, the value for common factors is 3120.

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 = 3088355212800/(1x3120)

LCM = 3088355212800/3120

LCM = 989857440

Thus, we can understand that the LCM of 121,416,855,260,276 is 989857440.
