Find LCM of 342,799,987,938 with Prime Factorization
| 2 | 342, 799, 987, 938 |
| 3 | 171, 799, 987, 469 |
| 7 | 57, 799, 329, 469 |
| 47 | 57, 799, 47, 67 |
| 57, 17, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 57 x 17 x 1 x 67 = 128158002
Therefore, the lowest common multiple of 342,799,987,938 is 128158002.
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.
342 x 799 x 987 x 938 = 252983895948
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
799 : 1, 17, 47, 799
987 : 1, 3, 7, 21, 47, 141, 329, 987
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,799,987,938, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
799:17x 47
987:3x 7x 47
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 47 = 1974
Therefore, the value for common factors is 1974.
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 = 252983895948/(1x1974)
LCM = 252983895948/1974
LCM = 128158002
Thus, we can understand that the LCM of 342,799,987,938 is 128158002.
