Given numbers are 46,6417,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 46,6417,620 is 128340.
Find LCM of 46,6417,620 with Prime Factorization
| 2 | 46, 6417, 620 |
| 23 | 23, 6417, 310 |
| 31 | 1, 279, 310 |
| 1, 9, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 31 x 1 x 9 x 10 = 128340
Therefore, the lowest common multiple of 46,6417,620 is 128340.
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.
46 x 6417 x 620 = 183012840
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.
46 : 1, 2, 23, 46
6417 : 1, 3, 9, 23, 31, 69, 93, 207, 279, 713, 2139, 6417
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 46,6417,620, is 1.
Now, the common factors can be found like this.
46:2x 23
6417:3x 3x 23x 31
620:2x 2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 31 = 1426
Therefore, the value for common factors is 1426.
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 = 183012840/(1x1426)
LCM = 183012840/1426
LCM = 128340
Thus, we can understand that the LCM of 46,6417,620 is 128340.
