Find LCM of 209,779,640,424,224 with Prime Factorization
| 2 | 209, 779, 640, 424, 224 |
| 2 | 209, 779, 320, 212, 112 |
| 2 | 209, 779, 160, 106, 56 |
| 2 | 209, 779, 80, 53, 28 |
| 2 | 209, 779, 40, 53, 14 |
| 19 | 209, 779, 20, 53, 7 |
| 11, 41, 20, 53, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 19 x 11 x 41 x 20 x 53 x 7 = 2034623360
Therefore, the lowest common multiple of 209,779,640,424,224 is 2034623360.
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 779 x 640 x 424 x 224 = 9896408023040
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
779 : 1, 19, 41, 779
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
424 : 1, 2, 4, 8, 53, 106, 212, 424
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,779,640,424,224, is 1.
Now, the common factors can be found like this.
209:11x 19
779:19x 41
640:2x 2x 2x 2x 2x 2x 2x 5
424:2x 2x 2x 53
224:2x 2x 2x 2x 2x 7
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 2x 2x 2x 2x 2x 19 = 4864
Therefore, the value for common factors is 4864.
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 = 9896408023040/(1x4864)
LCM = 9896408023040/4864
LCM = 2034623360
Thus, we can understand that the LCM of 209,779,640,424,224 is 2034623360.
