Given numbers are 766,943,287,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,943,287,643 is 3251243338.
Find LCM of 766,943,287,643 with Prime Factorization
41 | 766, 943, 287, 643 |
766, 23, 7, 643 |
Multiply the prime numbers at the bottom and the left side.
41 x 766 x 23 x 7 x 643 = 3251243338
Therefore, the lowest common multiple of 766,943,287,643 is 3251243338.
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.
766 x 943 x 287 x 643 = 133300976858
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.
766 : 1, 2, 383, 766
943 : 1, 23, 41, 943
287 : 1, 7, 41, 287
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,943,287,643, is 1.
Now, the common factors can be found like this.
766:2x 383
943:23x 41
287:7x 41
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41 = 41
Therefore, the value for common factors is 41.
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 = 133300976858/(1x41)
LCM = 133300976858/41
LCM = 3251243338
Thus, we can understand that the LCM of 766,943,287,643 is 3251243338.
