Find LCM of 312,752,777,143,686 with Prime Factorization
| 2 | 312, 752, 777, 143, 686 |
| 2 | 156, 376, 777, 143, 343 |
| 2 | 78, 188, 777, 143, 343 |
| 3 | 39, 94, 777, 143, 343 |
| 7 | 13, 94, 259, 143, 343 |
| 13 | 13, 94, 37, 143, 49 |
| 1, 94, 37, 11, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 1 x 94 x 37 x 11 x 49 = 4094218128
Therefore, the lowest common multiple of 312,752,777,143,686 is 4094218128.
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.
312 x 752 x 777 x 143 x 686 = 17883544783104
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
777 : 1, 3, 7, 21, 37, 111, 259, 777
143 : 1, 11, 13, 143
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,752,777,143,686, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
752:2x 2x 2x 2x 47
777:3x 7x 37
143:11x 13
686:2x 7x 7x 7
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 7x 13 = 4368
Therefore, the value for common factors is 4368.
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 = 17883544783104/(1x4368)
LCM = 17883544783104/4368
LCM = 4094218128
Thus, we can understand that the LCM of 312,752,777,143,686 is 4094218128.
