Given numbers are 550,878,870,386
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 550,878,870,386 is 4054186950.
Find LCM of 550,878,870,386 with Prime Factorization
| 2 | 550, 878, 870, 386 |
| 5 | 275, 439, 435, 193 |
| 55, 439, 87, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 55 x 439 x 87 x 193 = 4054186950
Therefore, the lowest common multiple of 550,878,870,386 is 4054186950.
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.
550 x 878 x 870 x 386 = 162167478000
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
878 : 1, 2, 439, 878
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
386 : 1, 2, 193, 386
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,878,870,386, is 2.
Now, the common factors can be found like this.
550:2x 5x 5x 11
878:2x 439
870:2x 3x 5x 29
386:2x 193
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 5 = 20
Therefore, the value for common factors is 20.
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 = 162167478000/(2x20)
LCM = 162167478000/40
LCM = 4054186950
Thus, we can understand that the LCM of 550,878,870,386 is 4054186950.
