Given numbers are 813,640,361,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,640,361,554 is 52030439040.
Find LCM of 813,640,361,554 with Prime Factorization
2 | 813, 640, 361, 554 |
813, 320, 361, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 813 x 320 x 361 x 277 = 52030439040
Therefore, the lowest common multiple of 813,640,361,554 is 52030439040.
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.
813 x 640 x 361 x 554 = 104060878080
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.
813 : 1, 3, 271, 813
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
361 : 1, 19, 361
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,640,361,554, is 1.
Now, the common factors can be found like this.
813:3x 271
640:2x 2x 2x 2x 2x 2x 2x 5
361:19x 19
554:2x 277
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 = 104060878080/(1x2)
LCM = 104060878080/2
LCM = 52030439040
Thus, we can understand that the LCM of 813,640,361,554 is 52030439040.
