Given numbers are 7,342,418,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,342,418,931 is 184338.
Find LCM of 7,342,418,931 with Prime Factorization
| 2 | 7, 342, 418, 931 |
| 7 | 7, 171, 209, 931 |
| 19 | 1, 171, 209, 133 |
| 1, 9, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 1 x 9 x 11 x 7 = 184338
Therefore, the lowest common multiple of 7,342,418,931 is 184338.
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.
7 x 342 x 418 x 931 = 931644252
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.
7 : 1, 7
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
418 : 1, 2, 11, 19, 22, 38, 209, 418
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,342,418,931, is 1.
Now, the common factors can be found like this.
7:7
342:2x 3x 3x 19
418:2x 11x 19
931:7x 7x 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 7x 19x 19 = 5054
Therefore, the value for common factors is 5054.
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 = 931644252/(1x5054)
LCM = 931644252/5054
LCM = 184338
Thus, we can understand that the LCM of 7,342,418,931 is 184338.
