Given numbers are 834,361,989,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,361,989,694 is 103323478542.
Find LCM of 834,361,989,694 with Prime Factorization
| 2 | 834, 361, 989, 694 |
| 417, 361, 989, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 417 x 361 x 989 x 347 = 103323478542
Therefore, the lowest common multiple of 834,361,989,694 is 103323478542.
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.
834 x 361 x 989 x 694 = 206646957084
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
361 : 1, 19, 361
989 : 1, 23, 43, 989
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,361,989,694, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
361:19x 19
989:23x 43
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 206646957084/(1x2)
LCM = 206646957084/2
LCM = 103323478542
Thus, we can understand that the LCM of 834,361,989,694 is 103323478542.
