Find LCM of 510,490,323,756 with Prime Factorization
| 2 | 510, 490, 323, 756 |
| 3 | 255, 245, 323, 378 |
| 5 | 85, 245, 323, 126 |
| 7 | 17, 49, 323, 126 |
| 17 | 17, 7, 323, 18 |
| 1, 7, 19, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 17 x 1 x 7 x 19 x 18 = 8546580
Therefore, the lowest common multiple of 510,490,323,756 is 8546580.
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.
510 x 490 x 323 x 756 = 61022581200
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
323 : 1, 17, 19, 323
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,490,323,756, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
490:2x 5x 7x 7
323:17x 19
756:2x 2x 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 2x 3x 5x 7x 17 = 7140
Therefore, the value for common factors is 7140.
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 = 61022581200/(1x7140)
LCM = 61022581200/7140
LCM = 8546580
Thus, we can understand that the LCM of 510,490,323,756 is 8546580.
