The LCM of 989,745,166,230,387 is 1100786670.
Find LCM of 989,745,166,230,387 with Prime Factorization
| 2 | 989, 745, 166, 230, 387 |
| 5 | 989, 745, 83, 115, 387 |
| 23 | 989, 149, 83, 23, 387 |
| 43 | 43, 149, 83, 1, 387 |
| 1, 149, 83, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 43 x 1 x 149 x 83 x 1 x 9 = 1100786670
Therefore, the lowest common multiple of 989,745,166,230,387 is 1100786670.
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.
989 x 745 x 166 x 230 x 387 = 10886780166300
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.
989 : 1, 23, 43, 989
745 : 1, 5, 149, 745
166 : 1, 2, 83, 166
230 : 1, 2, 5, 10, 23, 46, 115, 230
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,745,166,230,387, is 1.
Now, the common factors can be found like this.
989:23x 43
745:5x 149
166:2x 83
230:2x 5x 23
387:3x 3x 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 5x 23x 43 = 9890
Therefore, the value for common factors is 9890.
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 = 10886780166300/(1x9890)
LCM = 10886780166300/9890
LCM = 1100786670
Thus, we can understand that the LCM of 989,745,166,230,387 is 1100786670.
