Given numbers are 388,706,931,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,706,931,521 is 66434525164.
Find LCM of 388,706,931,521 with Prime Factorization
2 | 388, 706, 931, 521 |
194, 353, 931, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 194 x 353 x 931 x 521 = 66434525164
Therefore, the lowest common multiple of 388,706,931,521 is 66434525164.
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.
388 x 706 x 931 x 521 = 132869050328
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.
388 : 1, 2, 4, 97, 194, 388
706 : 1, 2, 353, 706
931 : 1, 7, 19, 49, 133, 931
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,706,931,521, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
706:2x 353
931:7x 7x 19
521:521
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 = 132869050328/(1x2)
LCM = 132869050328/2
LCM = 66434525164
Thus, we can understand that the LCM of 388,706,931,521 is 66434525164.
Here are some samples of LCM of two or more Numbers calculations.
