Given numbers are 505,890,991

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

The LCM of 505,890,991 is 89080990.

Find LCM of 505,890,991 with Prime Factorization

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

5 x 101 x 178 x 991 = 89080990

Therefore, the lowest common multiple of 505,890,991 is 89080990.

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.

505 x 890 x 991 = 445404950

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.

505 : 1, 5, 101, 505

890 : 1, 2, 5, 10, 89, 178, 445, 890

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,890,991, is 1.

Now, the common factors can be found like this.

505:5x 101

890:2x 5x 89

991:991

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

5 = 5

Therefore, the value for common factors is 5.

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 = 445404950/(1x5)

LCM = 445404950/5

LCM = 89080990

Thus, we can understand that the LCM of 505,890,991 is 89080990.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 137, 819, 571
• LCM of 384, 773, 381
• LCM of 273, 313, 908
