Given numbers are 391,410,796,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,410,796,360 is 1148460840.
Find LCM of 391,410,796,360 with Prime Factorization
| 2 | 391, 410, 796, 360 |
| 2 | 391, 205, 398, 180 |
| 5 | 391, 205, 199, 90 |
| 391, 41, 199, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 391 x 41 x 199 x 18 = 1148460840
Therefore, the lowest common multiple of 391,410,796,360 is 1148460840.
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.
391 x 410 x 796 x 360 = 45938433600
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.
391 : 1, 17, 23, 391
410 : 1, 2, 5, 10, 41, 82, 205, 410
796 : 1, 2, 4, 199, 398, 796
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,410,796,360, is 1.
Now, the common factors can be found like this.
391:17x 23
410:2x 5x 41
796:2x 2x 199
360:2x 2x 2x 3x 3x 5
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 5 = 40
Therefore, the value for common factors is 40.
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 = 45938433600/(1x40)
LCM = 45938433600/40
LCM = 1148460840
Thus, we can understand that the LCM of 391,410,796,360 is 1148460840.
