Given numbers are 821,187,924,263,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,187,924,263,945 is 152627331780.
Find LCM of 821,187,924,263,945 with Prime Factorization
| 3 | 821, 187, 924, 263, 945 |
| 7 | 821, 187, 308, 263, 315 |
| 11 | 821, 187, 44, 263, 45 |
| 821, 17, 4, 263, 45 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 821 x 17 x 4 x 263 x 45 = 152627331780
Therefore, the lowest common multiple of 821,187,924,263,945 is 152627331780.
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.
821 x 187 x 924 x 263 x 945 = 35256913641180
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.
821 : 1, 821
187 : 1, 11, 17, 187
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
263 : 1, 263
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,187,924,263,945, is 1.
Now, the common factors can be found like this.
821:821
187:11x 17
924:2x 2x 3x 7x 11
263:263
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 35256913641180/(1x231)
LCM = 35256913641180/231
LCM = 152627331780
Thus, we can understand that the LCM of 821,187,924,263,945 is 152627331780.
