Given numbers are 921,872,458,446,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,872,458,446,894 is 6110865555096.
Find LCM of 921,872,458,446,894 with Prime Factorization
| 2 | 921, 872, 458, 446, 894 |
| 3 | 921, 436, 229, 223, 447 |
| 307, 436, 229, 223, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 436 x 229 x 223 x 149 = 6110865555096
Therefore, the lowest common multiple of 921,872,458,446,894 is 6110865555096.
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.
921 x 872 x 458 x 446 x 894 = 146660773322304
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.
921 : 1, 3, 307, 921
872 : 1, 2, 4, 8, 109, 218, 436, 872
458 : 1, 2, 229, 458
446 : 1, 2, 223, 446
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,872,458,446,894, is 1.
Now, the common factors can be found like this.
921:3x 307
872:2x 2x 2x 109
458:2x 229
446:2x 223
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 146660773322304/(1x24)
LCM = 146660773322304/24
LCM = 6110865555096
Thus, we can understand that the LCM of 921,872,458,446,894 is 6110865555096.
