Given numbers are 986,189,230,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,189,230,644 is 42861420.
Find LCM of 986,189,230,644 with Prime Factorization
2 | 986, 189, 230, 644 |
7 | 493, 189, 115, 322 |
23 | 493, 27, 115, 46 |
493, 27, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 493 x 27 x 5 x 2 = 42861420
Therefore, the lowest common multiple of 986,189,230,644 is 42861420.
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.
986 x 189 x 230 x 644 = 27602754480
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
189 : 1, 3, 7, 9, 21, 27, 63, 189
230 : 1, 2, 5, 10, 23, 46, 115, 230
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 986,189,230,644, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
189:3x 3x 3x 7
230:2x 5x 23
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 7x 23 = 644
Therefore, the value for common factors is 644.
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 = 27602754480/(1x644)
LCM = 27602754480/644
LCM = 42861420
Thus, we can understand that the LCM of 986,189,230,644 is 42861420.
