Given numbers are 391,364,866,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,364,866,988 is 1170899548.
Find LCM of 391,364,866,988 with Prime Factorization
| 2 | 391, 364, 866, 988 |
| 2 | 391, 182, 433, 494 |
| 13 | 391, 91, 433, 247 |
| 391, 7, 433, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 391 x 7 x 433 x 19 = 1170899548
Therefore, the lowest common multiple of 391,364,866,988 is 1170899548.
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.
391 x 364 x 866 x 988 = 121773552992
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.
391 : 1, 17, 23, 391
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
866 : 1, 2, 433, 866
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,364,866,988, is 1.
Now, the common factors can be found like this.
391:17x 23
364:2x 2x 7x 13
866:2x 433
988:2x 2x 13x 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 2x 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 121773552992/(1x104)
LCM = 121773552992/104
LCM = 1170899548
Thus, we can understand that the LCM of 391,364,866,988 is 1170899548.
