Given numbers are 669,425,145,357,411
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,425,145,357,411 is 7907362575.
Find LCM of 669,425,145,357,411 with Prime Factorization
| 3 | 669, 425, 145, 357, 411 |
| 5 | 223, 425, 145, 119, 137 |
| 17 | 223, 85, 29, 119, 137 |
| 223, 5, 29, 7, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 223 x 5 x 29 x 7 x 137 = 7907362575
Therefore, the lowest common multiple of 669,425,145,357,411 is 7907362575.
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.
669 x 425 x 145 x 357 x 411 = 6049132369875
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.
669 : 1, 3, 223, 669
425 : 1, 5, 17, 25, 85, 425
145 : 1, 5, 29, 145
357 : 1, 3, 7, 17, 21, 51, 119, 357
411 : 1, 3, 137, 411
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,425,145,357,411, is 1.
Now, the common factors can be found like this.
669:3x 223
425:5x 5x 17
145:5x 29
357:3x 7x 17
411:3x 137
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 17 = 765
Therefore, the value for common factors is 765.
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 = 6049132369875/(1x765)
LCM = 6049132369875/765
LCM = 7907362575
Thus, we can understand that the LCM of 669,425,145,357,411 is 7907362575.
