Given numbers are 5,420,150,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 5,420,150,668 is 350700.
Find LCM of 5,420,150,668 with Prime Factorization
2 | 5, 420, 150, 668 |
2 | 5, 210, 75, 334 |
3 | 5, 105, 75, 167 |
5 | 5, 35, 25, 167 |
1, 7, 5, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 1 x 7 x 5 x 167 = 350700
Therefore, the lowest common multiple of 5,420,150,668 is 350700.
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.
5 x 420 x 150 x 668 = 210420000
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.
5 : 1, 5
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5,420,150,668, is 1.
Now, the common factors can be found like this.
5:5
420:2x 2x 3x 5x 7
150:2x 3x 5x 5
668:2x 2x 167
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 5 = 600
Therefore, the value for common factors is 600.
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 = 210420000/(1x600)
LCM = 210420000/600
LCM = 350700
Thus, we can understand that the LCM of 5,420,150,668 is 350700.
