Given numbers are 710,687,651,131,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 710,687,651,131,945 is 124792540110.
Find LCM of 710,687,651,131,945 with Prime Factorization
| 3 | 710, 687, 651, 131, 945 |
| 5 | 710, 229, 217, 131, 315 |
| 7 | 142, 229, 217, 131, 63 |
| 142, 229, 31, 131, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 142 x 229 x 31 x 131 x 9 = 124792540110
Therefore, the lowest common multiple of 710,687,651,131,945 is 124792540110.
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.
710 x 687 x 651 x 131 x 945 = 39309650134650
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.
710 : 1, 2, 5, 10, 71, 142, 355, 710
687 : 1, 3, 229, 687
651 : 1, 3, 7, 21, 31, 93, 217, 651
131 : 1, 131
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 710,687,651,131,945, is 1.
Now, the common factors can be found like this.
710:2x 5x 71
687:3x 229
651:3x 7x 31
131:131
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 39309650134650/(1x315)
LCM = 39309650134650/315
LCM = 124792540110
Thus, we can understand that the LCM of 710,687,651,131,945 is 124792540110.
