Given numbers are 821,604,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,604,906 is 1487652.
Find LCM of 821,604,906 with Prime Factorization
| 2 | 821, 604, 906 |
| 151 | 821, 302, 453 |
| 821, 2, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 151 x 821 x 2 x 3 = 1487652
Therefore, the lowest common multiple of 821,604,906 is 1487652.
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.
821 x 604 x 906 = 449270904
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.
821 : 1, 821
604 : 1, 2, 4, 151, 302, 604
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,604,906, is 1.
Now, the common factors can be found like this.
821:821
604:2x 2x 151
906:2x 3x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 151 = 302
Therefore, the value for common factors is 302.
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 = 449270904/(1x302)
LCM = 449270904/302
LCM = 1487652
Thus, we can understand that the LCM of 821,604,906 is 1487652.
