Given numbers are 631,492,243,915,512
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,492,243,915,512 is 981723732480.
Find LCM of 631,492,243,915,512 with Prime Factorization
| 2 | 631, 492, 243, 915, 512 |
| 2 | 631, 246, 243, 915, 256 |
| 3 | 631, 123, 243, 915, 128 |
| 631, 41, 81, 305, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 631 x 41 x 81 x 305 x 128 = 981723732480
Therefore, the lowest common multiple of 631,492,243,915,512 is 981723732480.
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 492 x 243 x 915 x 512 = 35342054369280
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
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
243 : 1, 3, 9, 27, 81, 243
915 : 1, 3, 5, 15, 61, 183, 305, 915
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,492,243,915,512, is 1.
Now, the common factors can be found like this.
631:631
492:2x 2x 3x 41
243:3x 3x 3x 3x 3
915:3x 5x 61
512:2x 2x 2x 2x 2x 2x 2x 2x 2
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 35342054369280/(1x36)
LCM = 35342054369280/36
LCM = 981723732480
Thus, we can understand that the LCM of 631,492,243,915,512 is 981723732480.
