Given numbers are 449,397,931,608,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 449,397,931,608,315 is 238973101920.
Find LCM of 449,397,931,608,315 with Prime Factorization
| 7 | 449, 397, 931, 608, 315 |
| 19 | 449, 397, 133, 608, 45 |
| 449, 397, 7, 32, 45 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 449 x 397 x 7 x 32 x 45 = 238973101920
Therefore, the lowest common multiple of 449,397,931,608,315 is 238973101920.
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.
449 x 397 x 931 x 608 x 315 = 31783422555360
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.
449 : 1, 449
397 : 1, 397
931 : 1, 7, 19, 49, 133, 931
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,397,931,608,315, is 1.
Now, the common factors can be found like this.
449:449
397:397
931:7x 7x 19
608:2x 2x 2x 2x 2x 19
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 31783422555360/(1x133)
LCM = 31783422555360/133
LCM = 238973101920
Thus, we can understand that the LCM of 449,397,931,608,315 is 238973101920.
