Given numbers are 386,787,992,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,787,992,255 is 38422347360.
Find LCM of 386,787,992,255 with Prime Factorization
| 2 | 386, 787, 992, 255 |
| 193, 787, 496, 255 |
Multiply the prime numbers at the bottom and the left side.
2 x 193 x 787 x 496 x 255 = 38422347360
Therefore, the lowest common multiple of 386,787,992,255 is 38422347360.
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.
386 x 787 x 992 x 255 = 76844694720
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.
386 : 1, 2, 193, 386
787 : 1, 787
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,787,992,255, is 1.
Now, the common factors can be found like this.
386:2x 193
787:787
992:2x 2x 2x 2x 2x 31
255:3x 5x 17
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 = 76844694720/(1x2)
LCM = 76844694720/2
LCM = 38422347360
Thus, we can understand that the LCM of 386,787,992,255 is 38422347360.
