Find LCM of 308,407,438,819,983 with Prime Factorization
| 2 | 308, 407, 438, 819, 983 |
| 3 | 154, 407, 219, 819, 983 |
| 7 | 154, 407, 73, 273, 983 |
| 11 | 22, 407, 73, 39, 983 |
| 2, 37, 73, 39, 983 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 2 x 37 x 73 x 39 x 983 = 95678570988
Therefore, the lowest common multiple of 308,407,438,819,983 is 95678570988.
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.
308 x 407 x 438 x 819 x 983 = 44203499796456
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
407 : 1, 11, 37, 407
438 : 1, 2, 3, 6, 73, 146, 219, 438
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,407,438,819,983, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
407:11x 37
438:2x 3x 73
819:3x 3x 7x 13
983:983
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 44203499796456/(1x462)
LCM = 44203499796456/462
LCM = 95678570988
Thus, we can understand that the LCM of 308,407,438,819,983 is 95678570988.
