Find LCM of 432,721,189,108,298 with Prime Factorization
| 2 | 432, 721, 189, 108, 298 |
| 2 | 216, 721, 189, 54, 149 |
| 3 | 108, 721, 189, 27, 149 |
| 3 | 36, 721, 63, 9, 149 |
| 3 | 12, 721, 21, 3, 149 |
| 7 | 4, 721, 7, 1, 149 |
| 4, 103, 1, 1, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 7 x 4 x 103 x 1 x 1 x 149 = 46409328
Therefore, the lowest common multiple of 432,721,189,108,298 is 46409328.
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.
432 x 721 x 189 x 108 x 298 = 1894614406272
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
721 : 1, 7, 103, 721
189 : 1, 3, 7, 9, 21, 27, 63, 189
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,721,189,108,298, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
721:7x 103
189:3x 3x 3x 7
108:2x 2x 3x 3x 3
298:2x 149
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 3x 3x 3x 3x 3x 3x 7 = 40824
Therefore, the value for common factors is 40824.
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 = 1894614406272/(1x40824)
LCM = 1894614406272/40824
LCM = 46409328
Thus, we can understand that the LCM of 432,721,189,108,298 is 46409328.
