Given numbers are 427,353,549,990,684

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

The LCM of 427,353,549,990,684 is 5670500220.

Find LCM of 427,353,549,990,684 with Prime Factorization

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

2 x 3 x 3 x 61 x 7 x 353 x 1 x 55 x 38 = 5670500220

Therefore, the lowest common multiple of 427,353,549,990,684 is 5670500220.

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.

427 x 353 x 549 x 990 x 684 = 56035883174040

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.

427 : 1, 7, 61, 427

353 : 1, 353

549 : 1, 3, 9, 61, 183, 549

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,353,549,990,684, is 1.

Now, the common factors can be found like this.

427:7x 61

353:353

549:3x 3x 61

990:2x 3x 3x 5x 11

684:2x 2x 3x 3x 19

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

2x 3x 3x 3x 3x 61 = 9882

Therefore, the value for common factors is 9882.

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 = 56035883174040/(1x9882)

LCM = 56035883174040/9882

LCM = 5670500220

Thus, we can understand that the LCM of 427,353,549,990,684 is 5670500220.
