Given numbers are 894,865,484,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,865,484,721 is 134928675420.
Find LCM of 894,865,484,721 with Prime Factorization
| 2 | 894, 865, 484, 721 |
| 447, 865, 242, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 447 x 865 x 242 x 721 = 134928675420
Therefore, the lowest common multiple of 894,865,484,721 is 134928675420.
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.
894 x 865 x 484 x 721 = 269857350840
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
865 : 1, 5, 173, 865
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,865,484,721, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
865:5x 173
484:2x 2x 11x 11
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 269857350840/(1x2)
LCM = 269857350840/2
LCM = 134928675420
Thus, we can understand that the LCM of 894,865,484,721 is 134928675420.
