Find LCM of 784,888,257,824,294 with Prime Factorization
| 2 | 784, 888, 257, 824, 294 |
| 2 | 392, 444, 257, 412, 147 |
| 2 | 196, 222, 257, 206, 147 |
| 3 | 98, 111, 257, 103, 147 |
| 7 | 98, 37, 257, 103, 49 |
| 7 | 14, 37, 257, 103, 7 |
| 2, 37, 257, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 2 x 37 x 257 x 103 x 1 = 2303612304
Therefore, the lowest common multiple of 784,888,257,824,294 is 2303612304.
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.
784 x 888 x 257 x 824 x 294 = 43344769112064
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
257 : 1, 257
824 : 1, 2, 4, 8, 103, 206, 412, 824
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,888,257,824,294, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
888:2x 2x 2x 3x 37
257:257
824:2x 2x 2x 103
294:2x 3x 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 3x 7x 7 = 18816
Therefore, the value for common factors is 18816.
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 = 43344769112064/(1x18816)
LCM = 43344769112064/18816
LCM = 2303612304
Thus, we can understand that the LCM of 784,888,257,824,294 is 2303612304.
