Find LCM of 128,392,944,733,980 with Prime Factorization
| 2 | 128, 392, 944, 733, 980 |
| 2 | 64, 196, 472, 733, 490 |
| 2 | 32, 98, 236, 733, 245 |
| 2 | 16, 49, 118, 733, 245 |
| 7 | 8, 49, 59, 733, 245 |
| 7 | 8, 7, 59, 733, 35 |
| 8, 1, 59, 733, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 7 x 8 x 1 x 59 x 733 x 5 = 1356225920
Therefore, the lowest common multiple of 128,392,944,733,980 is 1356225920.
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.
128 x 392 x 944 x 733 x 980 = 34024995880960
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
733 : 1, 733
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,392,944,733,980, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
392:2x 2x 2x 7x 7
944:2x 2x 2x 2x 59
733:733
980:2x 2x 5x 7x 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 2x 7x 7 = 25088
Therefore, the value for common factors is 25088.
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 = 34024995880960/(1x25088)
LCM = 34024995880960/25088
LCM = 1356225920
Thus, we can understand that the LCM of 128,392,944,733,980 is 1356225920.
