Given numbers are 428,915,170,599
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,915,170,599 is 3987866460.
Find LCM of 428,915,170,599 with Prime Factorization
| 2 | 428, 915, 170, 599 |
| 5 | 214, 915, 85, 599 |
| 214, 183, 17, 599 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 214 x 183 x 17 x 599 = 3987866460
Therefore, the lowest common multiple of 428,915,170,599 is 3987866460.
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.
428 x 915 x 170 x 599 = 39878664600
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.
428 : 1, 2, 4, 107, 214, 428
915 : 1, 3, 5, 15, 61, 183, 305, 915
170 : 1, 2, 5, 10, 17, 34, 85, 170
599 : 1, 599
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,915,170,599, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
915:3x 5x 61
170:2x 5x 17
599:599
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 39878664600/(1x10)
LCM = 39878664600/10
LCM = 3987866460
Thus, we can understand that the LCM of 428,915,170,599 is 3987866460.
