Find LCM of 109,784,224,481,860 with Prime Factorization
| 2 | 109, 784, 224, 481, 860 |
| 2 | 109, 392, 112, 481, 430 |
| 2 | 109, 196, 56, 481, 215 |
| 2 | 109, 98, 28, 481, 215 |
| 7 | 109, 49, 14, 481, 215 |
| 109, 7, 2, 481, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 109 x 7 x 2 x 481 x 215 = 17674864480
Therefore, the lowest common multiple of 109,784,224,481,860 is 17674864480.
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.
109 x 784 x 224 x 481 x 860 = 7918339287040
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.
109 : 1, 109
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
481 : 1, 13, 37, 481
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 109,784,224,481,860, is 1.
Now, the common factors can be found like this.
109:109
784:2x 2x 2x 2x 7x 7
224:2x 2x 2x 2x 2x 7
481:13x 37
860:2x 2x 5x 43
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 7 = 448
Therefore, the value for common factors is 448.
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 = 7918339287040/(1x448)
LCM = 7918339287040/448
LCM = 17674864480
Thus, we can understand that the LCM of 109,784,224,481,860 is 17674864480.
