Find LCM of 988,897,782,787,942 with Prime Factorization
| 2 | 988, 897, 782, 787, 942 |
| 3 | 494, 897, 391, 787, 471 |
| 13 | 494, 299, 391, 787, 157 |
| 23 | 38, 23, 391, 787, 157 |
| 38, 1, 17, 787, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 38 x 1 x 17 x 787 x 157 = 143195490516
Therefore, the lowest common multiple of 988,897,782,787,942 is 143195490516.
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 897 x 782 x 787 x 942 = 513785419971408
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
897 : 1, 3, 13, 23, 39, 69, 299, 897
782 : 1, 2, 17, 23, 34, 46, 391, 782
787 : 1, 787
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,897,782,787,942, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
897:3x 13x 23
782:2x 17x 23
787:787
942:2x 3x 157
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 3x 13x 23 = 3588
Therefore, the value for common factors is 3588.
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 = 513785419971408/(1x3588)
LCM = 513785419971408/3588
LCM = 143195490516
Thus, we can understand that the LCM of 988,897,782,787,942 is 143195490516.
