Given numbers are 686,766,188,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,766,188,993 is 24524490396.
Find LCM of 686,766,188,993 with Prime Factorization
2 | 686, 766, 188, 993 |
343, 383, 94, 993 |
Multiply the prime numbers at the bottom and the left side.
2 x 343 x 383 x 94 x 993 = 24524490396
Therefore, the lowest common multiple of 686,766,188,993 is 24524490396.
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.
686 x 766 x 188 x 993 = 98097961584
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
766 : 1, 2, 383, 766
188 : 1, 2, 4, 47, 94, 188
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,766,188,993, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
766:2x 383
188:2x 2x 47
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 98097961584/(1x4)
LCM = 98097961584/4
LCM = 24524490396
Thus, we can understand that the LCM of 686,766,188,993 is 24524490396.
