Given numbers are 805,902,642,338

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

The LCM of 805,902,642,338 is 39390741390.

Find LCM of 805,902,642,338 with Prime Factorization

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

2 x 805 x 451 x 321 x 169 = 39390741390

Therefore, the lowest common multiple of 805,902,642,338 is 39390741390.

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.

805 x 902 x 642 x 338 = 157562965560

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.

805 : 1, 5, 7, 23, 35, 115, 161, 805

902 : 1, 2, 11, 22, 41, 82, 451, 902

642 : 1, 2, 3, 6, 107, 214, 321, 642

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,902,642,338, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

902:2x 11x 41

642:2x 3x 107

338:2x 13x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 157562965560/(1x4)

LCM = 157562965560/4

LCM = 39390741390

Thus, we can understand that the LCM of 805,902,642,338 is 39390741390.

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