Given numbers are 863,871,640,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,871,640,793 is 29345313920.
Find LCM of 863,871,640,793 with Prime Factorization
13 | 863, 871, 640, 793 |
863, 67, 640, 61 |
Multiply the prime numbers at the bottom and the left side.
13 x 863 x 67 x 640 x 61 = 29345313920
Therefore, the lowest common multiple of 863,871,640,793 is 29345313920.
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.
863 x 871 x 640 x 793 = 381489080960
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.
863 : 1, 863
871 : 1, 13, 67, 871
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,871,640,793, is 1.
Now, the common factors can be found like this.
863:863
871:13x 67
640:2x 2x 2x 2x 2x 2x 2x 5
793:13x 61
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 = 381489080960/(1x13)
LCM = 381489080960/13
LCM = 29345313920
Thus, we can understand that the LCM of 863,871,640,793 is 29345313920.
