Given numbers are 403,648,955,989,403

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

The LCM of 403,648,955,989,403 is 246649202280.

Find LCM of 403,648,955,989,403 with Prime Factorization

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

13 x 31 x 1 x 648 x 955 x 989 x 1 = 246649202280

Therefore, the lowest common multiple of 403,648,955,989,403 is 246649202280.

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.

403 x 648 x 955 x 989 x 403 = 99399628518840

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.

403 : 1, 13, 31, 403

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

955 : 1, 5, 191, 955

989 : 1, 23, 43, 989

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,648,955,989,403, is 1.

Now, the common factors can be found like this.

403:13x 31

648:2x 2x 2x 3x 3x 3x 3

955:5x 191

989:23x 43

403:13x 31

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

13x 31 = 403

Therefore, the value for common factors is 403.

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 = 99399628518840/(1x403)

LCM = 99399628518840/403

LCM = 246649202280

Thus, we can understand that the LCM of 403,648,955,989,403 is 246649202280.
