Calculate the LCM of 845,988,817

Given numbers are 845,988,817

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

The LCM of 845,988,817 is 2761460.

Find LCM of 845,988,817 with Prime Factorization


13 845, 988, 817
19 65, 76, 817
65, 4, 43

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

13 x 19 x 65 x 4 x 43 = 2761460

Therefore, the lowest common multiple of 845,988,817 is 2761460.

LCM Formula to Find Lowest Common Multiple of 845,988,817

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.

845 x 988 x 817 = 682080620

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.

845 : 1, 5, 13, 65, 169, 845

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,988,817, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

988:2x 2x 13x 19

817:19x 43

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

13x 19 = 247

Therefore, the value for common factors is 247.

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 = 682080620/(1x247)

LCM = 682080620/247

LCM = 2761460

Thus, we can understand that the LCM of 845,988,817 is 2761460.
