Find LCM of 385,784,352,122,708 with Prime Factorization
| 2 | 385, 784, 352, 122, 708 |
| 2 | 385, 392, 176, 61, 354 |
| 2 | 385, 196, 88, 61, 177 |
| 2 | 385, 98, 44, 61, 177 |
| 7 | 385, 49, 22, 61, 177 |
| 11 | 55, 7, 22, 61, 177 |
| 5, 7, 2, 61, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 11 x 5 x 7 x 2 x 61 x 177 = 931133280
Therefore, the lowest common multiple of 385,784,352,122,708 is 931133280.
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.
385 x 784 x 352 x 122 x 708 = 9177249607680
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
122 : 1, 2, 61, 122
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,784,352,122,708, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
784:2x 2x 2x 2x 7x 7
352:2x 2x 2x 2x 2x 11
122:2x 61
708:2x 2x 3x 59
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 7x 11 = 9856
Therefore, the value for common factors is 9856.
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 = 9177249607680/(1x9856)
LCM = 9177249607680/9856
LCM = 931133280
Thus, we can understand that the LCM of 385,784,352,122,708 is 931133280.
