Find LCM of 786,393,247,684 with Prime Factorization
| 2 | 786, 393, 247, 684 |
| 3 | 393, 393, 247, 342 |
| 19 | 131, 131, 247, 114 |
| 131 | 131, 131, 13, 6 |
| 1, 1, 13, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 131 x 1 x 1 x 13 x 6 = 1164852
Therefore, the lowest common multiple of 786,393,247,684 is 1164852.
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.
786 x 393 x 247 x 684 = 52187699304
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
393 : 1, 3, 131, 393
247 : 1, 13, 19, 247
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,393,247,684, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
393:3x 131
247:13x 19
684:2x 2x 3x 3x 19
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 3x 19x 131 = 44802
Therefore, the value for common factors is 44802.
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 = 52187699304/(1x44802)
LCM = 52187699304/44802
LCM = 1164852
Thus, we can understand that the LCM of 786,393,247,684 is 1164852.
