Find LCM of 443,690,187,390,605 with Prime Factorization
2 | 443, 690, 187, 390, 605 |
3 | 443, 345, 187, 195, 605 |
5 | 443, 115, 187, 65, 605 |
11 | 443, 23, 187, 13, 121 |
443, 23, 17, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 443 x 23 x 17 x 13 x 11 = 8173921470
Therefore, the lowest common multiple of 443,690,187,390,605 is 8173921470.
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.
443 x 690 x 187 x 390 x 605 = 13486970425500
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.
443 : 1, 443
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
187 : 1, 11, 17, 187
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,690,187,390,605, is 1.
Now, the common factors can be found like this.
443:443
690:2x 3x 5x 23
187:11x 17
390:2x 3x 5x 13
605:5x 11x 11
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 5x 5x 11 = 1650
Therefore, the value for common factors is 1650.
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 = 13486970425500/(1x1650)
LCM = 13486970425500/1650
LCM = 8173921470
Thus, we can understand that the LCM of 443,690,187,390,605 is 8173921470.
