Given numbers are 815,989,651,782,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,989,651,782,745 is 2658276024810.
Find LCM of 815,989,651,782,745 with Prime Factorization
| 5 | 815, 989, 651, 782, 745 |
| 23 | 163, 989, 651, 782, 149 |
| 163, 43, 651, 34, 149 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 163 x 43 x 651 x 34 x 149 = 2658276024810
Therefore, the lowest common multiple of 815,989,651,782,745 is 2658276024810.
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.
815 x 989 x 651 x 782 x 745 = 305701742853150
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.
815 : 1, 5, 163, 815
989 : 1, 23, 43, 989
651 : 1, 3, 7, 21, 31, 93, 217, 651
782 : 1, 2, 17, 23, 34, 46, 391, 782
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,989,651,782,745, is 1.
Now, the common factors can be found like this.
815:5x 163
989:23x 43
651:3x 7x 31
782:2x 17x 23
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 305701742853150/(1x115)
LCM = 305701742853150/115
LCM = 2658276024810
Thus, we can understand that the LCM of 815,989,651,782,745 is 2658276024810.
