Find LCM of 988,346,992,536,247 with Prime Factorization
| 2 | 988, 346, 992, 536, 247 |
| 2 | 494, 173, 496, 268, 247 |
| 2 | 247, 173, 248, 134, 247 |
| 13 | 247, 173, 124, 67, 247 |
| 19 | 19, 173, 124, 67, 19 |
| 1, 173, 124, 67, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 19 x 1 x 173 x 124 x 67 x 1 = 2840073184
Therefore, the lowest common multiple of 988,346,992,536,247 is 2840073184.
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.
988 x 346 x 992 x 536 x 247 = 44895876892672
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
346 : 1, 2, 173, 346
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
536 : 1, 2, 4, 8, 67, 134, 268, 536
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,346,992,536,247, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
346:2x 173
992:2x 2x 2x 2x 2x 31
536:2x 2x 2x 67
247:13x 19
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 13x 19 = 15808
Therefore, the value for common factors is 15808.
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 = 44895876892672/(1x15808)
LCM = 44895876892672/15808
LCM = 2840073184
Thus, we can understand that the LCM of 988,346,992,536,247 is 2840073184.
