Given numbers are 451,991,176,649,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,991,176,649,721 is 304198771184.
Find LCM of 451,991,176,649,721 with Prime Factorization
| 11 | 451, 991, 176, 649, 721 |
| 41, 991, 16, 59, 721 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 991 x 16 x 59 x 721 = 304198771184
Therefore, the lowest common multiple of 451,991,176,649,721 is 304198771184.
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.
451 x 991 x 176 x 649 x 721 = 36808051313264
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.
451 : 1, 11, 41, 451
991 : 1, 991
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
649 : 1, 11, 59, 649
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,991,176,649,721, is 1.
Now, the common factors can be found like this.
451:11x 41
991:991
176:2x 2x 2x 2x 11
649:11x 59
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 36808051313264/(1x121)
LCM = 36808051313264/121
LCM = 304198771184
Thus, we can understand that the LCM of 451,991,176,649,721 is 304198771184.
