Find LCM of 518,209,420,448,805 with Prime Factorization
| 2 | 518, 209, 420, 448, 805 |
| 2 | 259, 209, 210, 224, 805 |
| 5 | 259, 209, 105, 112, 805 |
| 7 | 259, 209, 21, 112, 161 |
| 37, 209, 3, 16, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 37 x 209 x 3 x 16 x 23 = 1195212480
Therefore, the lowest common multiple of 518,209,420,448,805 is 1195212480.
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.
518 x 209 x 420 x 448 x 805 = 16398315225600
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
209 : 1, 11, 19, 209
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,209,420,448,805, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
209:11x 19
420:2x 2x 3x 5x 7
448:2x 2x 2x 2x 2x 2x 7
805:5x 7x 23
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 5x 7x 7x 7 = 13720
Therefore, the value for common factors is 13720.
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 = 16398315225600/(1x13720)
LCM = 16398315225600/13720
LCM = 1195212480
Thus, we can understand that the LCM of 518,209,420,448,805 is 1195212480.
