Find LCM of 645,930,630,298,522 with Prime Factorization
| 2 | 645, 930, 630, 298, 522 |
| 3 | 645, 465, 315, 149, 261 |
| 3 | 215, 155, 105, 149, 87 |
| 5 | 215, 155, 35, 149, 29 |
| 43, 31, 7, 149, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 43 x 31 x 7 x 149 x 29 = 3628732590
Therefore, the lowest common multiple of 645,930,630,298,522 is 3628732590.
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.
645 x 930 x 630 x 298 x 522 = 58785467958000
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
298 : 1, 2, 149, 298
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,930,630,298,522, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
930:2x 3x 5x 31
630:2x 3x 3x 5x 7
298:2x 149
522:2x 3x 3x 29
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 5x 5 = 16200
Therefore, the value for common factors is 16200.
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 = 58785467958000/(1x16200)
LCM = 58785467958000/16200
LCM = 3628732590
Thus, we can understand that the LCM of 645,930,630,298,522 is 3628732590.
