Find LCM of 380,956,428,665,412 with Prime Factorization
| 2 | 380, 956, 428, 665, 412 |
| 2 | 190, 478, 214, 665, 206 |
| 5 | 95, 239, 107, 665, 103 |
| 19 | 19, 239, 107, 133, 103 |
| 1, 239, 107, 7, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 1 x 239 x 107 x 7 x 103 = 7006490540
Therefore, the lowest common multiple of 380,956,428,665,412 is 7006490540.
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.
380 x 956 x 428 x 665 x 412 = 42599462483200
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
956 : 1, 2, 4, 239, 478, 956
428 : 1, 2, 4, 107, 214, 428
665 : 1, 5, 7, 19, 35, 95, 133, 665
412 : 1, 2, 4, 103, 206, 412
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,956,428,665,412, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
956:2x 2x 239
428:2x 2x 107
665:5x 7x 19
412:2x 2x 103
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 2x 2x 2x 5x 19 = 6080
Therefore, the value for common factors is 6080.
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 = 42599462483200/(1x6080)
LCM = 42599462483200/6080
LCM = 7006490540
Thus, we can understand that the LCM of 380,956,428,665,412 is 7006490540.
