Given numbers are 865,319,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,319,781 is 19591385.
Find LCM of 865,319,781 with Prime Factorization
11 | 865, 319, 781 |
865, 29, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 865 x 29 x 71 = 19591385
Therefore, the lowest common multiple of 865,319,781 is 19591385.
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.
865 x 319 x 781 = 215505235
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.
865 : 1, 5, 173, 865
319 : 1, 11, 29, 319
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,319,781, is 1.
Now, the common factors can be found like this.
865:5x 173
319:11x 29
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 215505235/(1x11)
LCM = 215505235/11
LCM = 19591385
Thus, we can understand that the LCM of 865,319,781 is 19591385.
