Given numbers are 834,647,921,970,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,647,921,970,215 is 3454768101030.
Find LCM of 834,647,921,970,215 with Prime Factorization
2 | 834, 647, 921, 970, 215 |
3 | 417, 647, 921, 485, 215 |
5 | 139, 647, 307, 485, 215 |
139, 647, 307, 97, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 647 x 307 x 97 x 43 = 3454768101030
Therefore, the lowest common multiple of 834,647,921,970,215 is 3454768101030.
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.
834 x 647 x 921 x 970 x 215 = 103643043030900
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
647 : 1, 647
921 : 1, 3, 307, 921
970 : 1, 2, 5, 10, 97, 194, 485, 970
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,647,921,970,215, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
647:647
921:3x 307
970:2x 5x 97
215:5x 43
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 5 = 30
Therefore, the value for common factors is 30.
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 = 103643043030900/(1x30)
LCM = 103643043030900/30
LCM = 3454768101030
Thus, we can understand that the LCM of 834,647,921,970,215 is 3454768101030.
