The LCM of 231,429,403,703 is 65444379.

Find LCM of 231,429,403,703 with Prime Factorization


3 231, 429, 403, 703
11 77, 143, 403, 703
13 7, 13, 403, 703
7, 1, 31, 703

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

3 x 11 x 13 x 7 x 1 x 31 x 703 = 65444379

Therefore, the lowest common multiple of 231,429,403,703 is 65444379.

LCM Formula to Find Lowest Common Multiple of 231,429,403,703

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.

231 x 429 x 403 x 703 = 28075638591

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

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

403 : 1, 13, 31, 403

703 : 1, 19, 37, 703

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,429,403,703, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

429:3x 11x 13

403:13x 31

703:19x 37

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

3x 11x 13 = 429

Therefore, the value for common factors is 429.

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 = 28075638591/(1x429)

LCM = 28075638591/429

LCM = 65444379

Thus, we can understand that the LCM of 231,429,403,703 is 65444379.
