Given numbers are 939,307,698,476,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,307,698,476,921 is 47889063852.
Find LCM of 939,307,698,476,921 with Prime Factorization
| 2 | 939, 307, 698, 476, 921 |
| 3 | 939, 307, 349, 238, 921 |
| 307 | 313, 307, 349, 238, 307 |
| 313, 1, 349, 238, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 313 x 1 x 349 x 238 x 1 = 47889063852
Therefore, the lowest common multiple of 939,307,698,476,921 is 47889063852.
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.
939 x 307 x 698 x 476 x 921 = 88211655615384
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.
939 : 1, 3, 313, 939
307 : 1, 307
698 : 1, 2, 349, 698
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,307,698,476,921, is 1.
Now, the common factors can be found like this.
939:3x 313
307:307
698:2x 349
476:2x 2x 7x 17
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 307 = 1842
Therefore, the value for common factors is 1842.
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 = 88211655615384/(1x1842)
LCM = 88211655615384/1842
LCM = 47889063852
Thus, we can understand that the LCM of 939,307,698,476,921 is 47889063852.
