Given numbers are 924,343,218,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 924,343,218,644 is 113506932.
Find LCM of 924,343,218,644 with Prime Factorization
2 | 924, 343, 218, 644 |
2 | 462, 343, 109, 322 |
7 | 231, 343, 109, 161 |
33, 49, 109, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 33 x 49 x 109 x 23 = 113506932
Therefore, the lowest common multiple of 924,343,218,644 is 113506932.
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.
924 x 343 x 218 x 644 = 44494717344
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.
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
343 : 1, 7, 49, 343
218 : 1, 2, 109, 218
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,343,218,644, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
343:7x 7x 7
218:2x 109
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 44494717344/(1x392)
LCM = 44494717344/392
LCM = 113506932
Thus, we can understand that the LCM of 924,343,218,644 is 113506932.
