Given numbers are 247,943,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,943,689 is 12344813.
Find LCM of 247,943,689 with Prime Factorization
13 | 247, 943, 689 |
19, 943, 53 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 943 x 53 = 12344813
Therefore, the lowest common multiple of 247,943,689 is 12344813.
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.
247 x 943 x 689 = 160482569
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.
247 : 1, 13, 19, 247
943 : 1, 23, 41, 943
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,943,689, is 1.
Now, the common factors can be found like this.
247:13x 19
943:23x 41
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 160482569/(1x13)
LCM = 160482569/13
LCM = 12344813
Thus, we can understand that the LCM of 247,943,689 is 12344813.
