Find LCM of 392,784,669,273,845 with Prime Factorization
| 2 | 392, 784, 669, 273, 845 |
| 2 | 196, 392, 669, 273, 845 |
| 2 | 98, 196, 669, 273, 845 |
| 3 | 49, 98, 669, 273, 845 |
| 7 | 49, 98, 223, 91, 845 |
| 7 | 7, 14, 223, 13, 845 |
| 13 | 1, 2, 223, 13, 845 |
| 1, 2, 223, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 13 x 1 x 2 x 223 x 1 x 65 = 443199120
Therefore, the lowest common multiple of 392,784,669,273,845 is 443199120.
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.
392 x 784 x 669 x 273 x 845 = 47429397025920
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
669 : 1, 3, 223, 669
273 : 1, 3, 7, 13, 21, 39, 91, 273
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,784,669,273,845, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
784:2x 2x 2x 2x 7x 7
669:3x 223
273:3x 7x 13
845:5x 13x 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 2x 3x 7x 7x 7x 13 = 107016
Therefore, the value for common factors is 107016.
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 = 47429397025920/(1x107016)
LCM = 47429397025920/107016
LCM = 443199120
Thus, we can understand that the LCM of 392,784,669,273,845 is 443199120.
