Given numbers are 704,772,316,711,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 704,772,316,711,821 is 79312698432.
Find LCM of 704,772,316,711,821 with Prime Factorization
| 2 | 704, 772, 316, 711, 821 |
| 2 | 352, 386, 158, 711, 821 |
| 79 | 176, 193, 79, 711, 821 |
| 176, 193, 1, 9, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 176 x 193 x 1 x 9 x 821 = 79312698432
Therefore, the lowest common multiple of 704,772,316,711,821 is 79312698432.
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.
704 x 772 x 316 x 711 x 821 = 100251250818048
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
772 : 1, 2, 4, 193, 386, 772
316 : 1, 2, 4, 79, 158, 316
711 : 1, 3, 9, 79, 237, 711
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,772,316,711,821, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
772:2x 2x 193
316:2x 2x 79
711:3x 3x 79
821:821
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 2x 79 = 1264
Therefore, the value for common factors is 1264.
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 = 100251250818048/(1x1264)
LCM = 100251250818048/1264
LCM = 79312698432
Thus, we can understand that the LCM of 704,772,316,711,821 is 79312698432.
