Given numbers are 375,646,100,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 375,646,100,489 is 78973500.
Find LCM of 375,646,100,489 with Prime Factorization
2 | 375, 646, 100, 489 |
3 | 375, 323, 50, 489 |
5 | 125, 323, 50, 163 |
5 | 25, 323, 10, 163 |
5, 323, 2, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 5 x 323 x 2 x 163 = 78973500
Therefore, the lowest common multiple of 375,646,100,489 is 78973500.
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.
375 x 646 x 100 x 489 = 11846025000
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.
375 : 1, 3, 5, 15, 25, 75, 125, 375
646 : 1, 2, 17, 19, 34, 38, 323, 646
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 375,646,100,489, is 1.
Now, the common factors can be found like this.
375:3x 5x 5x 5
646:2x 17x 19
100:2x 2x 5x 5
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 11846025000/(1x150)
LCM = 11846025000/150
LCM = 78973500
Thus, we can understand that the LCM of 375,646,100,489 is 78973500.
