Find LCM of 631,150,257,816,168 with Prime Factorization
| 2 | 631, 150, 257, 816, 168 |
| 2 | 631, 75, 257, 408, 84 |
| 2 | 631, 75, 257, 204, 42 |
| 3 | 631, 75, 257, 102, 21 |
| 631, 25, 257, 34, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 631 x 25 x 257 x 34 x 7 = 23157447600
Therefore, the lowest common multiple of 631,150,257,816,168 is 23157447600.
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.
631 x 150 x 257 x 816 x 168 = 3334672454400
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.
631 : 1, 631
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
257 : 1, 257
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,150,257,816,168, is 1.
Now, the common factors can be found like this.
631:631
150:2x 3x 5x 5
257:257
816:2x 2x 2x 2x 3x 17
168:2x 2x 2x 3x 7
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 3 = 144
Therefore, the value for common factors is 144.
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 = 3334672454400/(1x144)
LCM = 3334672454400/144
LCM = 23157447600
Thus, we can understand that the LCM of 631,150,257,816,168 is 23157447600.
