Find LCM of 143,168,102,857,661 with Prime Factorization
2 | 143, 168, 102, 857, 661 |
3 | 143, 84, 51, 857, 661 |
143, 28, 17, 857, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 143 x 28 x 17 x 857 x 661 = 231353738616
Therefore, the lowest common multiple of 143,168,102,857,661 is 231353738616.
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.
143 x 168 x 102 x 857 x 661 = 1388122431696
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.
143 : 1, 11, 13, 143
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
102 : 1, 2, 3, 6, 17, 34, 51, 102
857 : 1, 857
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,168,102,857,661, is 1.
Now, the common factors can be found like this.
143:11x 13
168:2x 2x 2x 3x 7
102:2x 3x 17
857:857
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 1388122431696/(1x6)
LCM = 1388122431696/6
LCM = 231353738616
Thus, we can understand that the LCM of 143,168,102,857,661 is 231353738616.
