Find LCM of 988,399,705,909,799 with Prime Factorization
| 3 | 988, 399, 705, 909, 799 |
| 19 | 988, 133, 235, 303, 799 |
| 47 | 52, 7, 235, 303, 799 |
| 52, 7, 5, 303, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 47 x 52 x 7 x 5 x 303 x 17 = 25115142780
Therefore, the lowest common multiple of 988,399,705,909,799 is 25115142780.
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 399 x 705 x 909 x 799 = 201850402522860
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
399 : 1, 3, 7, 19, 21, 57, 133, 399
705 : 1, 3, 5, 15, 47, 141, 235, 705
909 : 1, 3, 9, 101, 303, 909
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,399,705,909,799, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
399:3x 7x 19
705:3x 5x 47
909:3x 3x 101
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19x 47 = 8037
Therefore, the value for common factors is 8037.
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 = 201850402522860/(1x8037)
LCM = 201850402522860/8037
LCM = 25115142780
Thus, we can understand that the LCM of 988,399,705,909,799 is 25115142780.
