Given numbers are 929,648,960,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 929,648,960,781 is 18806230080.
Find LCM of 929,648,960,781 with Prime Factorization
| 2 | 929, 648, 960, 781 |
| 2 | 929, 324, 480, 781 |
| 2 | 929, 162, 240, 781 |
| 3 | 929, 81, 120, 781 |
| 929, 27, 40, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 929 x 27 x 40 x 781 = 18806230080
Therefore, the lowest common multiple of 929,648,960,781 is 18806230080.
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.
929 x 648 x 960 x 781 = 451349521920
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.
929 : 1, 929
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 929,648,960,781, is 1.
Now, the common factors can be found like this.
929:929
648:2x 2x 2x 3x 3x 3x 3
960:2x 2x 2x 2x 2x 2x 3x 5
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.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 451349521920/(1x24)
LCM = 451349521920/24
LCM = 18806230080
Thus, we can understand that the LCM of 929,648,960,781 is 18806230080.
