Given numbers are 431,668,431,471
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,668,431,471 is 135604668.
Find LCM of 431,668,431,471 with Prime Factorization
431 | 431, 668, 431, 471 |
1, 668, 1, 471 |
Multiply the prime numbers at the bottom and the left side.
431 x 1 x 668 x 1 x 471 = 135604668
Therefore, the lowest common multiple of 431,668,431,471 is 135604668.
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 668 x 431 x 471 = 58445611908
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
668 : 1, 2, 4, 167, 334, 668
431 : 1, 431
471 : 1, 3, 157, 471
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,668,431,471, is 1.
Now, the common factors can be found like this.
431:431
668:2x 2x 167
431:431
471:3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
431 = 431
Therefore, the value for common factors is 431.
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 = 58445611908/(1x431)
LCM = 58445611908/431
LCM = 135604668
Thus, we can understand that the LCM of 431,668,431,471 is 135604668.
