Find LCM of 986,395,901,615,978 with Prime Factorization
| 2 | 986, 395, 901, 615, 978 |
| 3 | 493, 395, 901, 615, 489 |
| 5 | 493, 395, 901, 205, 163 |
| 17 | 493, 79, 901, 41, 163 |
| 29, 79, 53, 41, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 29 x 79 x 53 x 41 x 163 = 413849653590
Therefore, the lowest common multiple of 986,395,901,615,978 is 413849653590.
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.
986 x 395 x 901 x 615 x 978 = 211063323330900
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
395 : 1, 5, 79, 395
901 : 1, 17, 53, 901
615 : 1, 3, 5, 15, 41, 123, 205, 615
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 986,395,901,615,978, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
395:5x 79
901:17x 53
615:3x 5x 41
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 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 211063323330900/(1x510)
LCM = 211063323330900/510
LCM = 413849653590
Thus, we can understand that the LCM of 986,395,901,615,978 is 413849653590.
