The LCM of 835,663,516,247,978 is 294896525820.
Find LCM of 835,663,516,247,978 with Prime Factorization
| 2 | 835, 663, 516, 247, 978 |
| 3 | 835, 663, 258, 247, 489 |
| 13 | 835, 221, 86, 247, 163 |
| 835, 17, 86, 19, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 835 x 17 x 86 x 19 x 163 = 294896525820
Therefore, the lowest common multiple of 835,663,516,247,978 is 294896525820.
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.
835 x 663 x 516 x 247 x 978 = 69005787041880
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.
835 : 1, 5, 167, 835
663 : 1, 3, 13, 17, 39, 51, 221, 663
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
247 : 1, 13, 19, 247
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,663,516,247,978, is 1.
Now, the common factors can be found like this.
835:5x 167
663:3x 13x 17
516:2x 2x 3x 43
247:13x 19
978:2x 3x 163
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 13 = 234
Therefore, the value for common factors is 234.
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 = 69005787041880/(1x234)
LCM = 69005787041880/234
LCM = 294896525820
Thus, we can understand that the LCM of 835,663,516,247,978 is 294896525820.
