Find LCM of 315,654,916,705,189 with Prime Factorization
| 2 | 315, 654, 916, 705, 189 |
| 3 | 315, 327, 458, 705, 189 |
| 3 | 105, 109, 458, 235, 63 |
| 5 | 35, 109, 458, 235, 21 |
| 7 | 7, 109, 458, 47, 21 |
| 1, 109, 458, 47, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 1 x 109 x 458 x 47 x 3 = 4434571260
Therefore, the lowest common multiple of 315,654,916,705,189 is 4434571260.
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.
315 x 654 x 916 x 705 x 189 = 25144019044200
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
654 : 1, 2, 3, 6, 109, 218, 327, 654
916 : 1, 2, 4, 229, 458, 916
705 : 1, 3, 5, 15, 47, 141, 235, 705
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,654,916,705,189, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
654:2x 3x 109
916:2x 2x 229
705:3x 5x 47
189:3x 3x 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 3x 3x 3x 3x 5x 7 = 5670
Therefore, the value for common factors is 5670.
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 = 25144019044200/(1x5670)
LCM = 25144019044200/5670
LCM = 4434571260
Thus, we can understand that the LCM of 315,654,916,705,189 is 4434571260.
