Given numbers are 969,817,771,412
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,817,771,412 is 4411868628.
Find LCM of 969,817,771,412 with Prime Factorization
| 3 | 969, 817, 771, 412 |
| 19 | 323, 817, 257, 412 |
| 17, 43, 257, 412 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 17 x 43 x 257 x 412 = 4411868628
Therefore, the lowest common multiple of 969,817,771,412 is 4411868628.
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.
969 x 817 x 771 x 412 = 251476511796
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
817 : 1, 19, 43, 817
771 : 1, 3, 257, 771
412 : 1, 2, 4, 103, 206, 412
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,817,771,412, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
817:19x 43
771:3x 257
412:2x 2x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 251476511796/(1x57)
LCM = 251476511796/57
LCM = 4411868628
Thus, we can understand that the LCM of 969,817,771,412 is 4411868628.
