Find LCM of 415,126,249,787,990 with Prime Factorization
| 2 | 415, 126, 249, 787, 990 |
| 3 | 415, 63, 249, 787, 495 |
| 3 | 415, 21, 83, 787, 165 |
| 5 | 415, 7, 83, 787, 55 |
| 83 | 83, 7, 83, 787, 11 |
| 1, 7, 1, 787, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 83 x 1 x 7 x 1 x 787 x 11 = 452674530
Therefore, the lowest common multiple of 415,126,249,787,990 is 452674530.
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.
415 x 126 x 249 x 787 x 990 = 10144436217300
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.
415 : 1, 5, 83, 415
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
249 : 1, 3, 83, 249
787 : 1, 787
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 415,126,249,787,990, is 1.
Now, the common factors can be found like this.
415:5x 83
126:2x 3x 3x 7
249:3x 83
787:787
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 5x 83 = 22410
Therefore, the value for common factors is 22410.
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 = 10144436217300/(1x22410)
LCM = 10144436217300/22410
LCM = 452674530
Thus, we can understand that the LCM of 415,126,249,787,990 is 452674530.
