Given numbers are 738,794,794,421,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,794,794,421,981 is 13444834554.
Find LCM of 738,794,794,421,981 with Prime Factorization
| 2 | 738, 794, 794, 421, 981 |
| 3 | 369, 397, 397, 421, 981 |
| 3 | 123, 397, 397, 421, 327 |
| 397 | 41, 397, 397, 421, 109 |
| 41, 1, 1, 421, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 397 x 41 x 1 x 1 x 421 x 109 = 13444834554
Therefore, the lowest common multiple of 738,794,794,421,981 is 13444834554.
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.
738 x 794 x 794 x 421 x 981 = 192153575445768
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
794 : 1, 2, 397, 794
794 : 1, 2, 397, 794
421 : 1, 421
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,794,794,421,981, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
794:2x 397
794:2x 397
421:421
981:3x 3x 109
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 397 = 14292
Therefore, the value for common factors is 14292.
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 = 192153575445768/(1x14292)
LCM = 192153575445768/14292
LCM = 13444834554
Thus, we can understand that the LCM of 738,794,794,421,981 is 13444834554.
