Given numbers are 403,318,742,839

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

The LCM of 403,318,742,839 is 752648442.

Find LCM of 403,318,742,839 with Prime Factorization

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

2 x 53 x 403 x 3 x 7 x 839 = 752648442

Therefore, the lowest common multiple of 403,318,742,839 is 752648442.

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 318 x 742 x 839 = 79780734852

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

318 : 1, 2, 3, 6, 53, 106, 159, 318

742 : 1, 2, 7, 14, 53, 106, 371, 742

839 : 1, 839

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,318,742,839, is 1.

Now, the common factors can be found like this.

403:13x 31

318:2x 3x 53

742:2x 7x 53

839:839

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 79780734852/(1x106)

LCM = 79780734852/106

LCM = 752648442

Thus, we can understand that the LCM of 403,318,742,839 is 752648442.
