Find LCM of 189,278,905,621,203 with Prime Factorization
3 | 189, 278, 905, 621, 203 |
3 | 63, 278, 905, 207, 203 |
3 | 21, 278, 905, 69, 203 |
7 | 7, 278, 905, 23, 203 |
1, 278, 905, 23, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 1 x 278 x 905 x 23 x 29 = 31716190170
Therefore, the lowest common multiple of 189,278,905,621,203 is 31716190170.
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.
189 x 278 x 905 x 621 x 203 = 5994359942130
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
278 : 1, 2, 139, 278
905 : 1, 5, 181, 905
621 : 1, 3, 9, 23, 27, 69, 207, 621
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,278,905,621,203, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
278:2x 139
905:5x 181
621:3x 3x 3x 23
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 5994359942130/(1x189)
LCM = 5994359942130/189
LCM = 31716190170
Thus, we can understand that the LCM of 189,278,905,621,203 is 31716190170.
