Given numbers are 421,838,157,731,482
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,838,157,731,482 is 9757985903906.
Find LCM of 421,838,157,731,482 with Prime Factorization
| 2 | 421, 838, 157, 731, 482 |
| 421, 419, 157, 731, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 421 x 419 x 157 x 731 x 241 = 9757985903906
Therefore, the lowest common multiple of 421,838,157,731,482 is 9757985903906.
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.
421 x 838 x 157 x 731 x 482 = 19515971807812
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.
421 : 1, 421
838 : 1, 2, 419, 838
157 : 1, 157
731 : 1, 17, 43, 731
482 : 1, 2, 241, 482
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,838,157,731,482, is 1.
Now, the common factors can be found like this.
421:421
838:2x 419
157:157
731:17x 43
482:2x 241
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 19515971807812/(1x2)
LCM = 19515971807812/2
LCM = 9757985903906
Thus, we can understand that the LCM of 421,838,157,731,482 is 9757985903906.
