Find LCM of 324,976,355,639 with Prime Factorization
| 2 | 324, 976, 355, 639 |
| 2 | 162, 488, 355, 639 |
| 3 | 81, 244, 355, 639 |
| 3 | 27, 244, 355, 213 |
| 71 | 9, 244, 355, 71 |
| 9, 244, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 71 x 9 x 244 x 5 x 1 = 28064880
Therefore, the lowest common multiple of 324,976,355,639 is 28064880.
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.
324 x 976 x 355 x 639 = 71733833280
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
355 : 1, 5, 71, 355
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,976,355,639, is 1.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
976:2x 2x 2x 2x 61
355:5x 71
639:3x 3x 71
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 71 = 2556
Therefore, the value for common factors is 2556.
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 = 71733833280/(1x2556)
LCM = 71733833280/2556
LCM = 28064880
Thus, we can understand that the LCM of 324,976,355,639 is 28064880.
