The LCM of 429,403,845,903 is 260194935.

Find LCM of 429,403,845,903 with Prime Factorization


3 429, 403, 845, 903
13 143, 403, 845, 301
11, 31, 65, 301

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

3 x 13 x 11 x 31 x 65 x 301 = 260194935

Therefore, the lowest common multiple of 429,403,845,903 is 260194935.

LCM Formula to Find Lowest Common Multiple of 429,403,845,903

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.

429 x 403 x 845 x 903 = 131918832045

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

403 : 1, 13, 31, 403

845 : 1, 5, 13, 65, 169, 845

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,403,845,903, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

403:13x 31

845:5x 13x 13

903:3x 7x 43

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

3x 13x 13 = 507

Therefore, the value for common factors is 507.

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 = 131918832045/(1x507)

LCM = 131918832045/507

LCM = 260194935

Thus, we can understand that the LCM of 429,403,845,903 is 260194935.
