Given numbers are 234,897,628,309,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 234,897,628,309,978 is 28372536972.
Find LCM of 234,897,628,309,978 with Prime Factorization
| 2 | 234, 897, 628, 309, 978 |
| 3 | 117, 897, 314, 309, 489 |
| 13 | 39, 299, 314, 103, 163 |
| 3, 23, 314, 103, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 3 x 23 x 314 x 103 x 163 = 28372536972
Therefore, the lowest common multiple of 234,897,628,309,978 is 28372536972.
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.
234 x 897 x 628 x 309 x 978 = 39835041908688
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
897 : 1, 3, 13, 23, 39, 69, 299, 897
628 : 1, 2, 4, 157, 314, 628
309 : 1, 3, 103, 309
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,897,628,309,978, is 1.
Now, the common factors can be found like this.
234:2x 3x 3x 13
897:3x 13x 23
628:2x 2x 157
309:3x 103
978:2x 3x 163
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 3x 3x 13 = 1404
Therefore, the value for common factors is 1404.
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 = 39835041908688/(1x1404)
LCM = 39835041908688/1404
LCM = 28372536972
Thus, we can understand that the LCM of 234,897,628,309,978 is 28372536972.
