Find LCM of 665,462,629,225,931 with Prime Factorization
| 3 | 665, 462, 629, 225, 931 |
| 5 | 665, 154, 629, 75, 931 |
| 7 | 133, 154, 629, 15, 931 |
| 19 | 19, 22, 629, 15, 133 |
| 1, 22, 629, 15, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 1 x 22 x 629 x 15 x 7 = 2898715050
Therefore, the lowest common multiple of 665,462,629,225,931 is 2898715050.
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.
665 x 462 x 629 x 225 x 931 = 40480555673250
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
629 : 1, 17, 37, 629
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,462,629,225,931, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
462:2x 3x 7x 11
629:17x 37
225:3x 3x 5x 5
931:7x 7x 19
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 7x 19 = 13965
Therefore, the value for common factors is 13965.
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 = 40480555673250/(1x13965)
LCM = 40480555673250/13965
LCM = 2898715050
Thus, we can understand that the LCM of 665,462,629,225,931 is 2898715050.
