Given numbers are 477,726,851,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 477,726,851,990 is 491171670.
Find LCM of 477,726,851,990 with Prime Factorization
| 2 | 477, 726, 851, 990 |
| 3 | 477, 363, 851, 495 |
| 3 | 159, 121, 851, 165 |
| 11 | 53, 121, 851, 55 |
| 53, 11, 851, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 53 x 11 x 851 x 5 = 491171670
Therefore, the lowest common multiple of 477,726,851,990 is 491171670.
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.
477 x 726 x 851 x 990 = 291755971980
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.
477 : 1, 3, 9, 53, 159, 477
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
851 : 1, 23, 37, 851
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,726,851,990, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
726:2x 3x 11x 11
851:23x 37
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 11 = 594
Therefore, the value for common factors is 594.
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 = 291755971980/(1x594)
LCM = 291755971980/594
LCM = 491171670
Thus, we can understand that the LCM of 477,726,851,990 is 491171670.
