Given numbers are 606,545,404,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 606,545,404,981 is 1981620.
Find LCM of 606,545,404,981 with Prime Factorization
| 2 | 606, 545, 404, 981 |
| 3 | 303, 545, 202, 981 |
| 101 | 101, 545, 202, 327 |
| 109 | 1, 545, 2, 327 |
| 1, 5, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 101 x 109 x 1 x 5 x 2 x 3 = 1981620
Therefore, the lowest common multiple of 606,545,404,981 is 1981620.
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.
606 x 545 x 404 x 981 = 130893927480
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.
606 : 1, 2, 3, 6, 101, 202, 303, 606
545 : 1, 5, 109, 545
404 : 1, 2, 4, 101, 202, 404
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,545,404,981, is 1.
Now, the common factors can be found like this.
606:2x 3x 101
545:5x 109
404:2x 2x 101
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 101x 109 = 66054
Therefore, the value for common factors is 66054.
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 = 130893927480/(1x66054)
LCM = 130893927480/66054
LCM = 1981620
Thus, we can understand that the LCM of 606,545,404,981 is 1981620.
