Given numbers are 646,391,800,948,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,391,800,948,964 is 339457754400.
Find LCM of 646,391,800,948,964 with Prime Factorization
| 2 | 646, 391, 800, 948, 964 |
| 2 | 323, 391, 400, 474, 482 |
| 17 | 323, 391, 200, 237, 241 |
| 19, 23, 200, 237, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 23 x 200 x 237 x 241 = 339457754400
Therefore, the lowest common multiple of 646,391,800,948,964 is 339457754400.
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.
646 x 391 x 800 x 948 x 964 = 184665018393600
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
391 : 1, 17, 23, 391
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,391,800,948,964, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
391:17x 23
800:2x 2x 2x 2x 2x 5x 5
948:2x 2x 3x 79
964:2x 2x 241
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 2x 2x 17 = 544
Therefore, the value for common factors is 544.
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 = 184665018393600/(1x544)
LCM = 184665018393600/544
LCM = 339457754400
Thus, we can understand that the LCM of 646,391,800,948,964 is 339457754400.
