Given numbers are 815,872,946,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,872,946,641 is 215473201240.
Find LCM of 815,872,946,641 with Prime Factorization
2 | 815, 872, 946, 641 |
815, 436, 473, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 815 x 436 x 473 x 641 = 215473201240
Therefore, the lowest common multiple of 815,872,946,641 is 215473201240.
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.
815 x 872 x 946 x 641 = 430946402480
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.
815 : 1, 5, 163, 815
872 : 1, 2, 4, 8, 109, 218, 436, 872
946 : 1, 2, 11, 22, 43, 86, 473, 946
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,872,946,641, is 1.
Now, the common factors can be found like this.
815:5x 163
872:2x 2x 2x 109
946:2x 11x 43
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 430946402480/(1x2)
LCM = 430946402480/2
LCM = 215473201240
Thus, we can understand that the LCM of 815,872,946,641 is 215473201240.
