Given numbers are 385,417,842,842

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

The LCM of 385,417,842,842 is 135178890.

Find LCM of 385,417,842,842 with Prime Factorization

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

2 x 421 x 385 x 417 x 1 x 1 = 135178890

Therefore, the lowest common multiple of 385,417,842,842 is 135178890.

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.

385 x 417 x 842 x 842 = 113820625380

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

417 : 1, 3, 139, 417

842 : 1, 2, 421, 842

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,417,842,842, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

417:3x 139

842:2x 421

842:2x 421

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

2x 421 = 842

Therefore, the value for common factors is 842.

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 = 113820625380/(1x842)

LCM = 113820625380/842

LCM = 135178890

Thus, we can understand that the LCM of 385,417,842,842 is 135178890.
