Given numbers are 315,609,445,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,609,445,667 is 18699345.
Find LCM of 315,609,445,667 with Prime Factorization
3 | 315, 609, 445, 667 |
5 | 105, 203, 445, 667 |
7 | 21, 203, 89, 667 |
29 | 3, 29, 89, 667 |
3, 1, 89, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 29 x 3 x 1 x 89 x 23 = 18699345
Therefore, the lowest common multiple of 315,609,445,667 is 18699345.
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.
315 x 609 x 445 x 667 = 56939505525
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
609 : 1, 3, 7, 21, 29, 87, 203, 609
445 : 1, 5, 89, 445
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,609,445,667, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
609:3x 7x 29
445:5x 89
667:23x 29
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 7x 29 = 3045
Therefore, the value for common factors is 3045.
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 = 56939505525/(1x3045)
LCM = 56939505525/3045
LCM = 18699345
Thus, we can understand that the LCM of 315,609,445,667 is 18699345.
