Given numbers are 815,506,698,639

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

The LCM of 815,506,698,639 is 91967506290.

Find LCM of 815,506,698,639 with Prime Factorization

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

2 x 815 x 253 x 349 x 639 = 91967506290

Therefore, the lowest common multiple of 815,506,698,639 is 91967506290.

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.

815 x 506 x 698 x 639 = 183935012580

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.

815 : 1, 5, 163, 815

506 : 1, 2, 11, 22, 23, 46, 253, 506

698 : 1, 2, 349, 698

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,506,698,639, is 1.

Now, the common factors can be found like this.

815:5x 163

506:2x 11x 23

698:2x 349

639:3x 3x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 183935012580/(1x2)

LCM = 183935012580/2

LCM = 91967506290

Thus, we can understand that the LCM of 815,506,698,639 is 91967506290.
