Find LCM of 168,290,576,972,718 with Prime Factorization
| 2 | 168, 290, 576, 972, 718 |
| 2 | 84, 145, 288, 486, 359 |
| 2 | 42, 145, 144, 243, 359 |
| 3 | 21, 145, 72, 243, 359 |
| 3 | 7, 145, 24, 81, 359 |
| 7, 145, 8, 27, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 145 x 8 x 27 x 359 = 5666915520
Therefore, the lowest common multiple of 168,290,576,972,718 is 5666915520.
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.
168 x 290 x 576 x 972 x 718 = 19584860037120
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
290 : 1, 2, 5, 10, 29, 58, 145, 290
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
718 : 1, 2, 359, 718
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,290,576,972,718, is 2.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
290:2x 5x 29
576:2x 2x 2x 2x 2x 2x 3x 3
972:2x 2x 3x 3x 3x 3x 3
718:2x 359
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 2x 3x 3x 3 = 1728
Therefore, the value for common factors is 1728.
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 = 19584860037120/(2x1728)
LCM = 19584860037120/3456
LCM = 5666915520
Thus, we can understand that the LCM of 168,290,576,972,718 is 5666915520.
