Find LCM of 418,120,660,665,937 with Prime Factorization
| 2 | 418, 120, 660, 665, 937 |
| 2 | 209, 60, 330, 665, 937 |
| 3 | 209, 30, 165, 665, 937 |
| 5 | 209, 10, 55, 665, 937 |
| 11 | 209, 2, 11, 133, 937 |
| 19 | 19, 2, 1, 133, 937 |
| 1, 2, 1, 7, 937 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 19 x 1 x 2 x 1 x 7 x 937 = 164499720
Therefore, the lowest common multiple of 418,120,660,665,937 is 164499720.
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.
418 x 120 x 660 x 665 x 937 = 20628264888000
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
665 : 1, 5, 7, 19, 35, 95, 133, 665
937 : 1, 937
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,120,660,665,937, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
120:2x 2x 2x 3x 5
660:2x 2x 3x 5x 11
665:5x 7x 19
937:937
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5x 5x 11x 19 = 125400
Therefore, the value for common factors is 125400.
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 = 20628264888000/(1x125400)
LCM = 20628264888000/125400
LCM = 164499720
Thus, we can understand that the LCM of 418,120,660,665,937 is 164499720.
