Find LCM of 709,455,855,338,651 with Prime Factorization
| 3 | 709, 455, 855, 338, 651 |
| 5 | 709, 455, 285, 338, 217 |
| 7 | 709, 91, 57, 338, 217 |
| 13 | 709, 13, 57, 338, 31 |
| 709, 1, 57, 26, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 13 x 709 x 1 x 57 x 26 x 31 = 44461978470
Therefore, the lowest common multiple of 709,455,855,338,651 is 44461978470.
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.
709 x 455 x 855 x 338 x 651 = 60690600611550
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.
709 : 1, 709
455 : 1, 5, 7, 13, 35, 65, 91, 455
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
338 : 1, 2, 13, 26, 169, 338
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,455,855,338,651, is 1.
Now, the common factors can be found like this.
709:709
455:5x 7x 13
855:3x 3x 5x 19
338:2x 13x 13
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 13 = 1365
Therefore, the value for common factors is 1365.
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 = 60690600611550/(1x1365)
LCM = 60690600611550/1365
LCM = 44461978470
Thus, we can understand that the LCM of 709,455,855,338,651 is 44461978470.
