Given numbers are 233,781,299,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 233,781,299,639 is 489689343.
Find LCM of 233,781,299,639 with Prime Factorization
| 71 | 233, 781, 299, 639 |
| 233, 11, 299, 9 |
Multiply the prime numbers at the bottom and the left side.
71 x 233 x 11 x 299 x 9 = 489689343
Therefore, the lowest common multiple of 233,781,299,639 is 489689343.
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.
233 x 781 x 299 x 639 = 34767943353
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.
233 : 1, 233
781 : 1, 11, 71, 781
299 : 1, 13, 23, 299
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 233,781,299,639, is 1.
Now, the common factors can be found like this.
233:233
781:11x 71
299:13x 23
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
71 = 71
Therefore, the value for common factors is 71.
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 = 34767943353/(1x71)
LCM = 34767943353/71
LCM = 489689343
Thus, we can understand that the LCM of 233,781,299,639 is 489689343.
