Given numbers are 676,838,849,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,838,849,572 is 2645215716.
Find LCM of 676,838,849,572 with Prime Factorization
| 2 | 676, 838, 849, 572 |
| 2 | 338, 419, 849, 286 |
| 13 | 169, 419, 849, 143 |
| 13, 419, 849, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 13 x 419 x 849 x 11 = 2645215716
Therefore, the lowest common multiple of 676,838,849,572 is 2645215716.
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.
676 x 838 x 849 x 572 = 275102434464
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
838 : 1, 2, 419, 838
849 : 1, 3, 283, 849
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,838,849,572, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
838:2x 419
849:3x 283
572:2x 2x 11x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 275102434464/(1x104)
LCM = 275102434464/104
LCM = 2645215716
Thus, we can understand that the LCM of 676,838,849,572 is 2645215716.
