Find LCM of 341,921,210,815,978 with Prime Factorization
| 2 | 341, 921, 210, 815, 978 |
| 3 | 341, 921, 105, 815, 489 |
| 5 | 341, 307, 35, 815, 163 |
| 163 | 341, 307, 7, 163, 163 |
| 341, 307, 7, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 163 x 341 x 307 x 7 x 1 x 1 = 3583436010
Therefore, the lowest common multiple of 341,921,210,815,978 is 3583436010.
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.
341 x 921 x 210 x 815 x 978 = 52569006266700
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.
341 : 1, 11, 31, 341
921 : 1, 3, 307, 921
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
815 : 1, 5, 163, 815
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 341,921,210,815,978, is 1.
Now, the common factors can be found like this.
341:11x 31
921:3x 307
210:2x 3x 5x 7
815:5x 163
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 5x 163 = 14670
Therefore, the value for common factors is 14670.
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 = 52569006266700/(1x14670)
LCM = 52569006266700/14670
LCM = 3583436010
Thus, we can understand that the LCM of 341,921,210,815,978 is 3583436010.
