Given numbers are 821,273,398,767

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

The LCM of 821,273,398,767 is 5263091106.

Find LCM of 821,273,398,767 with Prime Factorization

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

13 x 821 x 21 x 398 x 59 = 5263091106

Therefore, the lowest common multiple of 821,273,398,767 is 5263091106.

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.

821 x 273 x 398 x 767 = 68420184378

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.

821 : 1, 821

273 : 1, 3, 7, 13, 21, 39, 91, 273

398 : 1, 2, 199, 398

767 : 1, 13, 59, 767

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,273,398,767, is 1.

Now, the common factors can be found like this.

821:821

273:3x 7x 13

398:2x 199

767:13x 59

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

13 = 13

Therefore, the value for common factors is 13.

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 = 68420184378/(1x13)

LCM = 68420184378/13

LCM = 5263091106

Thus, we can understand that the LCM of 821,273,398,767 is 5263091106.
