Given numbers are 451,341,147,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,341,147,638 is 119202006.
Find LCM of 451,341,147,638 with Prime Factorization
| 11 | 451, 341, 147, 638 |
| 41, 31, 147, 58 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 31 x 147 x 58 = 119202006
Therefore, the lowest common multiple of 451,341,147,638 is 119202006.
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.
451 x 341 x 147 x 638 = 14423442726
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.
451 : 1, 11, 41, 451
341 : 1, 11, 31, 341
147 : 1, 3, 7, 21, 49, 147
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,341,147,638, is 1.
Now, the common factors can be found like this.
451:11x 41
341:11x 31
147:3x 7x 7
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 14423442726/(1x121)
LCM = 14423442726/121
LCM = 119202006
Thus, we can understand that the LCM of 451,341,147,638 is 119202006.
