The LCM of 678,290,493,867 is 28411590.
Find LCM of 678,290,493,867 with Prime Factorization
| 2 | 678, 290, 493, 867 |
| 3 | 339, 145, 493, 867 |
| 17 | 113, 145, 493, 289 |
| 29 | 113, 145, 29, 17 |
| 113, 5, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 29 x 113 x 5 x 1 x 17 = 28411590
Therefore, the lowest common multiple of 678,290,493,867 is 28411590.
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.
678 x 290 x 493 x 867 = 84041483220
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
290 : 1, 2, 5, 10, 29, 58, 145, 290
493 : 1, 17, 29, 493
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,290,493,867, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
290:2x 5x 29
493:17x 29
867:3x 17x 17
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 17x 29 = 2958
Therefore, the value for common factors is 2958.
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 = 84041483220/(1x2958)
LCM = 84041483220/2958
LCM = 28411590
Thus, we can understand that the LCM of 678,290,493,867 is 28411590.
