Find LCM of 209,988,549,468 with Prime Factorization
| 2 | 209, 988, 549, 468 |
| 2 | 209, 494, 549, 234 |
| 3 | 209, 247, 549, 117 |
| 3 | 209, 247, 183, 39 |
| 13 | 209, 247, 61, 13 |
| 19 | 209, 19, 61, 1 |
| 11, 1, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 19 x 11 x 1 x 61 x 1 = 5966532
Therefore, the lowest common multiple of 209,988,549,468 is 5966532.
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.
209 x 988 x 549 x 468 = 53054402544
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.
209 : 1, 11, 19, 209
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
549 : 1, 3, 9, 61, 183, 549
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,988,549,468, is 1.
Now, the common factors can be found like this.
209:11x 19
988:2x 2x 13x 19
549:3x 3x 61
468:2x 2x 3x 3x 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 3x 3x 13x 19 = 8892
Therefore, the value for common factors is 8892.
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 = 53054402544/(1x8892)
LCM = 53054402544/8892
LCM = 5966532
Thus, we can understand that the LCM of 209,988,549,468 is 5966532.
