Given numbers are 442,511,511,989

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

The LCM of 442,511,511,989 is 223377518.

Find LCM of 442,511,511,989 with Prime Factorization

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

7 x 73 x 442 x 1 x 1 x 989 = 223377518

Therefore, the lowest common multiple of 442,511,511,989 is 223377518.

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.

442 x 511 x 511 x 989 = 114145911698

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

511 : 1, 7, 73, 511

511 : 1, 7, 73, 511

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,511,511,989, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

511:7x 73

511:7x 73

989:23x 43

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

7x 73 = 511

Therefore, the value for common factors is 511.

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 = 114145911698/(1x511)

LCM = 114145911698/511

LCM = 223377518

Thus, we can understand that the LCM of 442,511,511,989 is 223377518.
