Calculate the LCM of 807,605,799,660

Given numbers are 807,605,799,660

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

The LCM of 807,605,799,660 is 1560399060.

Find LCM of 807,605,799,660 with Prime Factorization


3 807, 605, 799, 660
5 269, 605, 799, 220
11 269, 121, 799, 44
269, 11, 799, 4

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

3 x 5 x 11 x 269 x 11 x 799 x 4 = 1560399060

Therefore, the lowest common multiple of 807,605,799,660 is 1560399060.

LCM Formula to Find Lowest Common Multiple of 807,605,799,660

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.

807 x 605 x 799 x 660 = 257465844900

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.

807 : 1, 3, 269, 807

605 : 1, 5, 11, 55, 121, 605

799 : 1, 17, 47, 799

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,605,799,660, is 1.

Now, the common factors can be found like this.

807:3x 269

605:5x 11x 11

799:17x 47

660:2x 2x 3x 5x 11

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

3x 5x 11 = 165

Therefore, the value for common factors is 165.

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 = 257465844900/(1x165)

LCM = 257465844900/165

LCM = 1560399060

Thus, we can understand that the LCM of 807,605,799,660 is 1560399060.
