Given numbers are 254,300,455,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,300,455,442 is 58940700.
Find LCM of 254,300,455,442 with Prime Factorization
| 2 | 254, 300, 455, 442 |
| 5 | 127, 150, 455, 221 |
| 13 | 127, 30, 91, 221 |
| 127, 30, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 127 x 30 x 7 x 17 = 58940700
Therefore, the lowest common multiple of 254,300,455,442 is 58940700.
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.
254 x 300 x 455 x 442 = 15324582000
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.
254 : 1, 2, 127, 254
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
455 : 1, 5, 7, 13, 35, 65, 91, 455
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,300,455,442, is 1.
Now, the common factors can be found like this.
254:2x 127
300:2x 2x 3x 5x 5
455:5x 7x 13
442:2x 13x 17
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 15324582000/(1x260)
LCM = 15324582000/260
LCM = 58940700
Thus, we can understand that the LCM of 254,300,455,442 is 58940700.
