Given numbers are 477,692,838,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 477,692,838,908 is 31395279492.
Find LCM of 477,692,838,908 with Prime Factorization
| 2 | 477, 692, 838, 908 |
| 2 | 477, 346, 419, 454 |
| 477, 173, 419, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 477 x 173 x 419 x 227 = 31395279492
Therefore, the lowest common multiple of 477,692,838,908 is 31395279492.
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.
477 x 692 x 838 x 908 = 251162235936
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.
477 : 1, 3, 9, 53, 159, 477
692 : 1, 2, 4, 173, 346, 692
838 : 1, 2, 419, 838
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,692,838,908, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
692:2x 2x 173
838:2x 419
908:2x 2x 227
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 2 = 8
Therefore, the value for common factors is 8.
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 = 251162235936/(1x8)
LCM = 251162235936/8
LCM = 31395279492
Thus, we can understand that the LCM of 477,692,838,908 is 31395279492.
