Given numbers are 766,221,286,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,221,286,990 is 83796570.
Find LCM of 766,221,286,990 with Prime Factorization
| 2 | 766, 221, 286, 990 |
| 11 | 383, 221, 143, 495 |
| 13 | 383, 221, 13, 45 |
| 383, 17, 1, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 383 x 17 x 1 x 45 = 83796570
Therefore, the lowest common multiple of 766,221,286,990 is 83796570.
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.
766 x 221 x 286 x 990 = 47931638040
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.
766 : 1, 2, 383, 766
221 : 1, 13, 17, 221
286 : 1, 2, 11, 13, 22, 26, 143, 286
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 766,221,286,990, is 1.
Now, the common factors can be found like this.
766:2x 383
221:13x 17
286:2x 11x 13
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 2x 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 47931638040/(1x572)
LCM = 47931638040/572
LCM = 83796570
Thus, we can understand that the LCM of 766,221,286,990 is 83796570.
