Find LCM of 560,189,448,646,605 with Prime Factorization
| 2 | 560, 189, 448, 646, 605 |
| 2 | 280, 189, 224, 323, 605 |
| 2 | 140, 189, 112, 323, 605 |
| 2 | 70, 189, 56, 323, 605 |
| 5 | 35, 189, 28, 323, 605 |
| 7 | 7, 189, 28, 323, 121 |
| 1, 27, 4, 323, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 1 x 27 x 4 x 323 x 121 = 2363739840
Therefore, the lowest common multiple of 560,189,448,646,605 is 2363739840.
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.
560 x 189 x 448 x 646 x 605 = 18531720345600
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
189 : 1, 3, 7, 9, 21, 27, 63, 189
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
646 : 1, 2, 17, 19, 34, 38, 323, 646
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 560,189,448,646,605, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
189:3x 3x 3x 7
448:2x 2x 2x 2x 2x 2x 7
646:2x 17x 19
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 2x 2x 2x 2x 5x 7x 7 = 7840
Therefore, the value for common factors is 7840.
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 = 18531720345600/(1x7840)
LCM = 18531720345600/7840
LCM = 2363739840
Thus, we can understand that the LCM of 560,189,448,646,605 is 2363739840.
