Given numbers are 214,341,420,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 214,341,420,842 is 6451631340.
Find LCM of 214,341,420,842 with Prime Factorization
| 2 | 214, 341, 420, 842 |
| 107, 341, 210, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 341 x 210 x 421 = 6451631340
Therefore, the lowest common multiple of 214,341,420,842 is 6451631340.
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.
214 x 341 x 420 x 842 = 25806525360
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.
214 : 1, 2, 107, 214
341 : 1, 11, 31, 341
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
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,341,420,842, is 1.
Now, the common factors can be found like this.
214:2x 107
341:11x 31
420:2x 2x 3x 5x 7
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 25806525360/(1x4)
LCM = 25806525360/4
LCM = 6451631340
Thus, we can understand that the LCM of 214,341,420,842 is 6451631340.
