The LCM of 888,168,722,494 is 29171688.
Find LCM of 888,168,722,494 with Prime Factorization
| 2 | 888, 168, 722, 494 |
| 2 | 444, 84, 361, 247 |
| 2 | 222, 42, 361, 247 |
| 3 | 111, 21, 361, 247 |
| 19 | 37, 7, 361, 247 |
| 37, 7, 19, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 37 x 7 x 19 x 13 = 29171688
Therefore, the lowest common multiple of 888,168,722,494 is 29171688.
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.
888 x 168 x 722 x 494 = 53209158912
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
722 : 1, 2, 19, 38, 361, 722
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,168,722,494, is 2.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
168:2x 2x 2x 3x 7
722:2x 19x 19
494:2x 13x 19
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 2x 3x 19 = 912
Therefore, the value for common factors is 912.
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 = 53209158912/(2x912)
LCM = 53209158912/1824
LCM = 29171688
Thus, we can understand that the LCM of 888,168,722,494 is 29171688.
