Given numbers are 964,654,660,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 964,654,660,803 is 1265640420.
Find LCM of 964,654,660,803 with Prime Factorization
| 2 | 964, 654, 660, 803 |
| 2 | 482, 327, 330, 803 |
| 3 | 241, 327, 165, 803 |
| 11 | 241, 109, 55, 803 |
| 241, 109, 5, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 241 x 109 x 5 x 73 = 1265640420
Therefore, the lowest common multiple of 964,654,660,803 is 1265640420.
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.
964 x 654 x 660 x 803 = 334129070880
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.
964 : 1, 2, 4, 241, 482, 964
654 : 1, 2, 3, 6, 109, 218, 327, 654
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,654,660,803, is 1.
Now, the common factors can be found like this.
964:2x 2x 241
654:2x 3x 109
660:2x 2x 3x 5x 11
803:11x 73
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 334129070880/(1x264)
LCM = 334129070880/264
LCM = 1265640420
Thus, we can understand that the LCM of 964,654,660,803 is 1265640420.
