Find LCM of 980,518,391,585,323 with Prime Factorization
2 | 980, 518, 391, 585, 323 |
5 | 490, 259, 391, 585, 323 |
7 | 98, 259, 391, 117, 323 |
17 | 14, 37, 391, 117, 323 |
14, 37, 23, 117, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 17 x 14 x 37 x 23 x 117 x 19 = 31516938180
Therefore, the lowest common multiple of 980,518,391,585,323 is 31516938180.
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.
980 x 518 x 391 x 585 x 323 = 37505156434200
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
518 : 1, 2, 7, 14, 37, 74, 259, 518
391 : 1, 17, 23, 391
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,518,391,585,323, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
518:2x 7x 37
391:17x 23
585:3x 3x 5x 13
323:17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 17 = 1190
Therefore, the value for common factors is 1190.
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 = 37505156434200/(1x1190)
LCM = 37505156434200/1190
LCM = 31516938180
Thus, we can understand that the LCM of 980,518,391,585,323 is 31516938180.
