Given numbers are 383,262,869,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 383,262,869,420 is 18312141540.
Find LCM of 383,262,869,420 with Prime Factorization
| 2 | 383, 262, 869, 420 |
| 383, 131, 869, 210 |
Multiply the prime numbers at the bottom and the left side.
2 x 383 x 131 x 869 x 210 = 18312141540
Therefore, the lowest common multiple of 383,262,869,420 is 18312141540.
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.
383 x 262 x 869 x 420 = 36624283080
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.
383 : 1, 383
262 : 1, 2, 131, 262
869 : 1, 11, 79, 869
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 383,262,869,420, is 1.
Now, the common factors can be found like this.
383:383
262:2x 131
869:11x 79
420:2x 2x 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.
2 = 2
Therefore, the value for common factors is 2.
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 = 36624283080/(1x2)
LCM = 36624283080/2
LCM = 18312141540
Thus, we can understand that the LCM of 383,262,869,420 is 18312141540.
