Given numbers are 763,815,639,438

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

The LCM of 763,815,639,438 is 58014407430.

Find LCM of 763,815,639,438 with Prime Factorization

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

3 x 763 x 815 x 213 x 146 = 58014407430

Therefore, the lowest common multiple of 763,815,639,438 is 58014407430.

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.

763 x 815 x 639 x 438 = 174043222290

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.

763 : 1, 7, 109, 763

815 : 1, 5, 163, 815

639 : 1, 3, 9, 71, 213, 639

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,815,639,438, is 1.

Now, the common factors can be found like this.

763:7x 109

815:5x 163

639:3x 3x 71

438:2x 3x 73

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

3 = 3

Therefore, the value for common factors is 3.

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 = 174043222290/(1x3)

LCM = 174043222290/3

LCM = 58014407430

Thus, we can understand that the LCM of 763,815,639,438 is 58014407430.
