Find LCM of 660,323,517,490,748 with Prime Factorization
2 | 660, 323, 517, 490, 748 |
2 | 330, 323, 517, 245, 374 |
5 | 165, 323, 517, 245, 187 |
11 | 33, 323, 517, 49, 187 |
17 | 3, 323, 47, 49, 17 |
3, 19, 47, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 17 x 3 x 19 x 47 x 49 x 1 = 490953540
Therefore, the lowest common multiple of 660,323,517,490,748 is 490953540.
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.
660 x 323 x 517 x 490 x 748 = 40395657271200
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
323 : 1, 17, 19, 323
517 : 1, 11, 47, 517
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,323,517,490,748, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
323:17x 19
517:11x 47
490:2x 5x 7x 7
748:2x 2x 11x 17
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 5x 11x 11x 17 = 82280
Therefore, the value for common factors is 82280.
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 = 40395657271200/(1x82280)
LCM = 40395657271200/82280
LCM = 490953540
Thus, we can understand that the LCM of 660,323,517,490,748 is 490953540.
