Find LCM of 991,968,363,584 with Prime Factorization
| 2 | 991, 968, 363, 584 |
| 2 | 991, 484, 363, 292 |
| 2 | 991, 242, 363, 146 |
| 11 | 991, 121, 363, 73 |
| 11 | 991, 11, 33, 73 |
| 991, 1, 3, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 11 x 991 x 1 x 3 x 73 = 210084072
Therefore, the lowest common multiple of 991,968,363,584 is 210084072.
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.
991 x 968 x 363 x 584 = 203361381696
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.
991 : 1, 991
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
363 : 1, 3, 11, 33, 121, 363
584 : 1, 2, 4, 8, 73, 146, 292, 584
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,968,363,584, is 1.
Now, the common factors can be found like this.
991:991
968:2x 2x 2x 11x 11
363:3x 11x 11
584:2x 2x 2x 73
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 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 203361381696/(1x968)
LCM = 203361381696/968
LCM = 210084072
Thus, we can understand that the LCM of 991,968,363,584 is 210084072.
