Given numbers are 255,900,871,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 255,900,871,646 is 253199700.
Find LCM of 255,900,871,646 with Prime Factorization
2 | 255, 900, 871, 646 |
3 | 255, 450, 871, 323 |
5 | 85, 150, 871, 323 |
17 | 17, 30, 871, 323 |
1, 30, 871, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 1 x 30 x 871 x 19 = 253199700
Therefore, the lowest common multiple of 255,900,871,646 is 253199700.
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.
255 x 900 x 871 x 646 = 129131847000
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
871 : 1, 13, 67, 871
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,900,871,646, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
900:2x 2x 3x 3x 5x 5
871:13x 67
646:2x 17x 19
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 17 = 510
Therefore, the value for common factors is 510.
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 = 129131847000/(1x510)
LCM = 129131847000/510
LCM = 253199700
Thus, we can understand that the LCM of 255,900,871,646 is 253199700.
