Given numbers are 279,310,990,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,310,990,515 is 3161070.
Find LCM of 279,310,990,515 with Prime Factorization
| 2 | 279, 310, 990, 515 |
| 3 | 279, 155, 495, 515 |
| 3 | 93, 155, 165, 515 |
| 5 | 31, 155, 55, 515 |
| 31 | 31, 31, 11, 103 |
| 1, 1, 11, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 31 x 1 x 1 x 11 x 103 = 3161070
Therefore, the lowest common multiple of 279,310,990,515 is 3161070.
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.
279 x 310 x 990 x 515 = 44096926500
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.
279 : 1, 3, 9, 31, 93, 279
310 : 1, 2, 5, 10, 31, 62, 155, 310
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,310,990,515, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
310:2x 5x 31
990:2x 3x 3x 5x 11
515:5x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 31 = 13950
Therefore, the value for common factors is 13950.
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 = 44096926500/(1x13950)
LCM = 44096926500/13950
LCM = 3161070
Thus, we can understand that the LCM of 279,310,990,515 is 3161070.
