The LCM of 408,752,723,986 is 268042128.
Find LCM of 408,752,723,986 with Prime Factorization
| 2 | 408, 752, 723, 986 |
| 2 | 204, 376, 723, 493 |
| 2 | 102, 188, 723, 493 |
| 3 | 51, 94, 723, 493 |
| 17 | 17, 94, 241, 493 |
| 1, 94, 241, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 1 x 94 x 241 x 29 = 268042128
Therefore, the lowest common multiple of 408,752,723,986 is 268042128.
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.
408 x 752 x 723 x 986 = 218722376448
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
723 : 1, 3, 241, 723
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,752,723,986, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
752:2x 2x 2x 2x 47
723:3x 241
986:2x 17x 29
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 3x 17 = 816
Therefore, the value for common factors is 816.
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 = 218722376448/(1x816)
LCM = 218722376448/816
LCM = 268042128
Thus, we can understand that the LCM of 408,752,723,986 is 268042128.
