Given numbers are 989,699,233,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,699,233,686 is 474239346.
Find LCM of 989,699,233,686 with Prime Factorization
| 233 | 989, 699, 233, 686 |
| 989, 3, 1, 686 |
Multiply the prime numbers at the bottom and the left side.
233 x 989 x 3 x 1 x 686 = 474239346
Therefore, the lowest common multiple of 989,699,233,686 is 474239346.
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.
989 x 699 x 233 x 686 = 110497767618
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.
989 : 1, 23, 43, 989
699 : 1, 3, 233, 699
233 : 1, 233
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,699,233,686, is 1.
Now, the common factors can be found like this.
989:23x 43
699:3x 233
233:233
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
233 = 233
Therefore, the value for common factors is 233.
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 = 110497767618/(1x233)
LCM = 110497767618/233
LCM = 474239346
Thus, we can understand that the LCM of 989,699,233,686 is 474239346.
