Find LCM of 985,642,992,248,479 with Prime Factorization
| 2 | 985, 642, 992, 248, 479 |
| 2 | 985, 321, 496, 124, 479 |
| 2 | 985, 321, 248, 62, 479 |
| 31 | 985, 321, 124, 31, 479 |
| 985, 321, 4, 1, 479 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 985 x 321 x 4 x 1 x 479 = 150240994080
Therefore, the lowest common multiple of 985,642,992,248,479 is 150240994080.
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.
985 x 642 x 992 x 248 x 479 = 74519533063680
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.
985 : 1, 5, 197, 985
642 : 1, 2, 3, 6, 107, 214, 321, 642
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
248 : 1, 2, 4, 8, 31, 62, 124, 248
479 : 1, 479
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,642,992,248,479, is 1.
Now, the common factors can be found like this.
985:5x 197
642:2x 3x 107
992:2x 2x 2x 2x 2x 31
248:2x 2x 2x 31
479:479
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 31 = 496
Therefore, the value for common factors is 496.
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 = 74519533063680/(1x496)
LCM = 74519533063680/496
LCM = 150240994080
Thus, we can understand that the LCM of 985,642,992,248,479 is 150240994080.
