Find LCM of 961,830,448,160 with Prime Factorization
| 2 | 961, 830, 448, 160 |
| 2 | 961, 415, 224, 80 |
| 2 | 961, 415, 112, 40 |
| 2 | 961, 415, 56, 20 |
| 2 | 961, 415, 28, 10 |
| 5 | 961, 415, 14, 5 |
| 961, 83, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 961 x 83 x 14 x 1 = 178669120
Therefore, the lowest common multiple of 961,830,448,160 is 178669120.
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.
961 x 830 x 448 x 160 = 57174118400
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.
961 : 1, 31, 961
830 : 1, 2, 5, 10, 83, 166, 415, 830
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,830,448,160, is 1.
Now, the common factors can be found like this.
961:31x 31
830:2x 5x 83
448:2x 2x 2x 2x 2x 2x 7
160:2x 2x 2x 2x 2x 5
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 5 = 320
Therefore, the value for common factors is 320.
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 = 57174118400/(1x320)
LCM = 57174118400/320
LCM = 178669120
Thus, we can understand that the LCM of 961,830,448,160 is 178669120.
