Given numbers are 425,677,649,418,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 425,677,649,418,990 is 63862865550.
Find LCM of 425,677,649,418,990 with Prime Factorization
| 2 | 425, 677, 649, 418, 990 |
| 5 | 425, 677, 649, 209, 495 |
| 11 | 85, 677, 649, 209, 99 |
| 85, 677, 59, 19, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 85 x 677 x 59 x 19 x 9 = 63862865550
Therefore, the lowest common multiple of 425,677,649,418,990 is 63862865550.
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.
425 x 677 x 649 x 418 x 990 = 77274067315500
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.
425 : 1, 5, 17, 25, 85, 425
677 : 1, 677
649 : 1, 11, 59, 649
418 : 1, 2, 11, 19, 22, 38, 209, 418
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 425,677,649,418,990, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
677:677
649:11x 59
418:2x 11x 19
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 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 77274067315500/(1x1210)
LCM = 77274067315500/1210
LCM = 63862865550
Thus, we can understand that the LCM of 425,677,649,418,990 is 63862865550.
