Given numbers are 287,451,631,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,451,631,181 is 360564127.
Find LCM of 287,451,631,181 with Prime Factorization
41 | 287, 451, 631, 181 |
7, 11, 631, 181 |
Multiply the prime numbers at the bottom and the left side.
41 x 7 x 11 x 631 x 181 = 360564127
Therefore, the lowest common multiple of 287,451,631,181 is 360564127.
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.
287 x 451 x 631 x 181 = 14783129207
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.
287 : 1, 7, 41, 287
451 : 1, 11, 41, 451
631 : 1, 631
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,451,631,181, is 1.
Now, the common factors can be found like this.
287:7x 41
451:11x 41
631:631
181:181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41 = 41
Therefore, the value for common factors is 41.
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 = 14783129207/(1x41)
LCM = 14783129207/41
LCM = 360564127
Thus, we can understand that the LCM of 287,451,631,181 is 360564127.
