Given numbers are 998,646,723,255,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,646,723,255,572 is 333278577060.
Find LCM of 998,646,723,255,572 with Prime Factorization
| 2 | 998, 646, 723, 255, 572 |
| 3 | 499, 323, 723, 255, 286 |
| 17 | 499, 323, 241, 85, 286 |
| 499, 19, 241, 5, 286 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 499 x 19 x 241 x 5 x 286 = 333278577060
Therefore, the lowest common multiple of 998,646,723,255,572 is 333278577060.
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.
998 x 646 x 723 x 255 x 572 = 67988829720240
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.
998 : 1, 2, 499, 998
646 : 1, 2, 17, 19, 34, 38, 323, 646
723 : 1, 3, 241, 723
255 : 1, 3, 5, 15, 17, 51, 85, 255
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,646,723,255,572, is 1.
Now, the common factors can be found like this.
998:2x 499
646:2x 17x 19
723:3x 241
255:3x 5x 17
572:2x 2x 11x 13
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 17 = 204
Therefore, the value for common factors is 204.
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 = 67988829720240/(1x204)
LCM = 67988829720240/204
LCM = 333278577060
Thus, we can understand that the LCM of 998,646,723,255,572 is 333278577060.
