Given numbers are 809,978,341,955,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,978,341,955,738 is 31692043139130.
Find LCM of 809,978,341,955,738 with Prime Factorization
| 2 | 809, 978, 341, 955, 738 |
| 3 | 809, 489, 341, 955, 369 |
| 809, 163, 341, 955, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 809 x 163 x 341 x 955 x 123 = 31692043139130
Therefore, the lowest common multiple of 809,978,341,955,738 is 31692043139130.
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.
809 x 978 x 341 x 955 x 738 = 190152258834780
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.
809 : 1, 809
978 : 1, 2, 3, 6, 163, 326, 489, 978
341 : 1, 11, 31, 341
955 : 1, 5, 191, 955
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,978,341,955,738, is 1.
Now, the common factors can be found like this.
809:809
978:2x 3x 163
341:11x 31
955:5x 191
738:2x 3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 190152258834780/(1x6)
LCM = 190152258834780/6
LCM = 31692043139130
Thus, we can understand that the LCM of 809,978,341,955,738 is 31692043139130.
