Given numbers are 631,446,822,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,446,822,936 is 18043909416.
Find LCM of 631,446,822,936 with Prime Factorization
| 2 | 631, 446, 822, 936 |
| 3 | 631, 223, 411, 468 |
| 631, 223, 137, 156 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 631 x 223 x 137 x 156 = 18043909416
Therefore, the lowest common multiple of 631,446,822,936 is 18043909416.
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.
631 x 446 x 822 x 936 = 216526912992
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.
631 : 1, 631
446 : 1, 2, 223, 446
822 : 1, 2, 3, 6, 137, 274, 411, 822
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,446,822,936, is 1.
Now, the common factors can be found like this.
631:631
446:2x 223
822:2x 3x 137
936:2x 2x 2x 3x 3x 13
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 3 = 12
Therefore, the value for common factors is 12.
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 = 216526912992/(1x12)
LCM = 216526912992/12
LCM = 18043909416
Thus, we can understand that the LCM of 631,446,822,936 is 18043909416.
