Given numbers are 431,379,147,987,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,379,147,987,255 is 95929150485.
Find LCM of 431,379,147,987,255 with Prime Factorization
| 3 | 431, 379, 147, 987, 255 |
| 7 | 431, 379, 49, 329, 85 |
| 431, 379, 7, 47, 85 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 431 x 379 x 7 x 47 x 85 = 95929150485
Therefore, the lowest common multiple of 431,379,147,987,255 is 95929150485.
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.
431 x 379 x 147 x 987 x 255 = 6043536480555
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.
431 : 1, 431
379 : 1, 379
147 : 1, 3, 7, 21, 49, 147
987 : 1, 3, 7, 21, 47, 141, 329, 987
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,379,147,987,255, is 1.
Now, the common factors can be found like this.
431:431
379:379
147:3x 7x 7
987:3x 7x 47
255:3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 6043536480555/(1x63)
LCM = 6043536480555/63
LCM = 95929150485
Thus, we can understand that the LCM of 431,379,147,987,255 is 95929150485.
