Given numbers are 782,667,353,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,667,353,989 is 344229362.
Find LCM of 782,667,353,989 with Prime Factorization
23 | 782, 667, 353, 989 |
34, 29, 353, 43 |
Multiply the prime numbers at the bottom and the left side.
23 x 34 x 29 x 353 x 43 = 344229362
Therefore, the lowest common multiple of 782,667,353,989 is 344229362.
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.
782 x 667 x 353 x 989 = 182097332498
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
667 : 1, 23, 29, 667
353 : 1, 353
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,667,353,989, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
667:23x 29
353:353
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 182097332498/(1x529)
LCM = 182097332498/529
LCM = 344229362
Thus, we can understand that the LCM of 782,667,353,989 is 344229362.
