Given numbers are 279,920,260,140,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,920,260,140,355 is 1658409480.
Find LCM of 279,920,260,140,355 with Prime Factorization
| 2 | 279, 920, 260, 140, 355 |
| 2 | 279, 460, 130, 70, 355 |
| 5 | 279, 230, 65, 35, 355 |
| 279, 46, 13, 7, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 279 x 46 x 13 x 7 x 71 = 1658409480
Therefore, the lowest common multiple of 279,920,260,140,355 is 1658409480.
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 920 x 260 x 140 x 355 = 3316818960000
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,920,260,140,355, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
920:2x 2x 2x 5x 23
260:2x 2x 5x 13
140:2x 2x 5x 7
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 5x 5 = 2000
Therefore, the value for common factors is 2000.
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 = 3316818960000/(1x2000)
LCM = 3316818960000/2000
LCM = 1658409480
Thus, we can understand that the LCM of 279,920,260,140,355 is 1658409480.
