Given numbers are 969,722,407,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,722,407,418 is 14986554.
Find LCM of 969,722,407,418 with Prime Factorization
| 2 | 969, 722, 407, 418 |
| 11 | 969, 361, 407, 209 |
| 19 | 969, 361, 37, 19 |
| 51, 1, 37, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 51 x 1 x 37 x 19 = 14986554
Therefore, the lowest common multiple of 969,722,407,418 is 14986554.
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 722 x 407 x 418 = 119023211868
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
722 : 1, 2, 19, 38, 361, 722
407 : 1, 11, 37, 407
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,722,407,418, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
722:2x 19x 19
407:11x 37
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 19x 19 = 7942
Therefore, the value for common factors is 7942.
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 = 119023211868/(1x7942)
LCM = 119023211868/7942
LCM = 14986554
Thus, we can understand that the LCM of 969,722,407,418 is 14986554.
