Given numbers are 347,689,286,922,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,689,286,922,990 is 109115090370.
Find LCM of 347,689,286,922,990 with Prime Factorization
| 2 | 347, 689, 286, 922, 990 |
| 11 | 347, 689, 143, 461, 495 |
| 13 | 347, 689, 13, 461, 45 |
| 347, 53, 1, 461, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 347 x 53 x 1 x 461 x 45 = 109115090370
Therefore, the lowest common multiple of 347,689,286,922,990 is 109115090370.
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.
347 x 689 x 286 x 922 x 990 = 62413831691640
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.
347 : 1, 347
689 : 1, 13, 53, 689
286 : 1, 2, 11, 13, 22, 26, 143, 286
922 : 1, 2, 461, 922
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 347,689,286,922,990, is 1.
Now, the common factors can be found like this.
347:347
689:13x 53
286:2x 11x 13
922:2x 461
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 = 62413831691640/(1x572)
LCM = 62413831691640/572
LCM = 109115090370
Thus, we can understand that the LCM of 347,689,286,922,990 is 109115090370.
