Given numbers are 669,391,556,556,331
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,391,556,556,331 is 48139952844.
Find LCM of 669,391,556,556,331 with Prime Factorization
2 | 669, 391, 556, 556, 331 |
2 | 669, 391, 278, 278, 331 |
139 | 669, 391, 139, 139, 331 |
669, 391, 1, 1, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 669 x 391 x 1 x 1 x 331 = 48139952844
Therefore, the lowest common multiple of 669,391,556,556,331 is 48139952844.
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.
669 x 391 x 556 x 556 x 331 = 26765813781264
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.
669 : 1, 3, 223, 669
391 : 1, 17, 23, 391
556 : 1, 2, 4, 139, 278, 556
556 : 1, 2, 4, 139, 278, 556
331 : 1, 331
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,391,556,556,331, is 1.
Now, the common factors can be found like this.
669:3x 223
391:17x 23
556:2x 2x 139
556:2x 2x 139
331:331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 139 = 556
Therefore, the value for common factors is 556.
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 = 26765813781264/(1x556)
LCM = 26765813781264/556
LCM = 48139952844
Thus, we can understand that the LCM of 669,391,556,556,331 is 48139952844.
