Given numbers are 215,951,145,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,951,145,821 is 4868107185.
Find LCM of 215,951,145,821 with Prime Factorization
5 | 215, 951, 145, 821 |
43, 951, 29, 821 |
Multiply the prime numbers at the bottom and the left side.
5 x 43 x 951 x 29 x 821 = 4868107185
Therefore, the lowest common multiple of 215,951,145,821 is 4868107185.
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.
215 x 951 x 145 x 821 = 24340535925
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.
215 : 1, 5, 43, 215
951 : 1, 3, 317, 951
145 : 1, 5, 29, 145
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,951,145,821, is 1.
Now, the common factors can be found like this.
215:5x 43
951:3x 317
145:5x 29
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 24340535925/(1x5)
LCM = 24340535925/5
LCM = 4868107185
Thus, we can understand that the LCM of 215,951,145,821 is 4868107185.
