Given numbers are 457,838,262,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,838,262,988 is 24783261724.
Find LCM of 457,838,262,988 with Prime Factorization
| 2 | 457, 838, 262, 988 |
| 457, 419, 131, 494 |
Multiply the prime numbers at the bottom and the left side.
2 x 457 x 419 x 131 x 494 = 24783261724
Therefore, the lowest common multiple of 457,838,262,988 is 24783261724.
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.
457 x 838 x 262 x 988 = 99133046896
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.
457 : 1, 457
838 : 1, 2, 419, 838
262 : 1, 2, 131, 262
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,838,262,988, is 1.
Now, the common factors can be found like this.
457:457
838:2x 419
262:2x 131
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 99133046896/(1x4)
LCM = 99133046896/4
LCM = 24783261724
Thus, we can understand that the LCM of 457,838,262,988 is 24783261724.
