Given numbers are 755,666,450,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,666,450,415 is 208674450.
Find LCM of 755,666,450,415 with Prime Factorization
| 2 | 755, 666, 450, 415 |
| 3 | 755, 333, 225, 415 |
| 3 | 755, 111, 75, 415 |
| 5 | 755, 37, 25, 415 |
| 151, 37, 5, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 151 x 37 x 5 x 83 = 208674450
Therefore, the lowest common multiple of 755,666,450,415 is 208674450.
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.
755 x 666 x 450 x 415 = 93903502500
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.
755 : 1, 5, 151, 755
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,666,450,415, is 1.
Now, the common factors can be found like this.
755:5x 151
666:2x 3x 3x 37
450:2x 3x 3x 5x 5
415:5x 83
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 93903502500/(1x450)
LCM = 93903502500/450
LCM = 208674450
Thus, we can understand that the LCM of 755,666,450,415 is 208674450.
