Given numbers are 315,398,994,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,398,994,517 is 4601956590.
Find LCM of 315,398,994,517 with Prime Factorization
| 2 | 315, 398, 994, 517 |
| 7 | 315, 199, 497, 517 |
| 45, 199, 71, 517 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 45 x 199 x 71 x 517 = 4601956590
Therefore, the lowest common multiple of 315,398,994,517 is 4601956590.
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 398 x 994 x 517 = 64427392260
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
398 : 1, 2, 199, 398
994 : 1, 2, 7, 14, 71, 142, 497, 994
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,398,994,517, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
398:2x 199
994:2x 7x 71
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 64427392260/(1x14)
LCM = 64427392260/14
LCM = 4601956590
Thus, we can understand that the LCM of 315,398,994,517 is 4601956590.
