Given numbers are 189,407,613,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,407,613,924 is 188615196.
Find LCM of 189,407,613,924 with Prime Factorization
| 3 | 189, 407, 613, 924 |
| 7 | 63, 407, 613, 308 |
| 11 | 9, 407, 613, 44 |
| 9, 37, 613, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 9 x 37 x 613 x 4 = 188615196
Therefore, the lowest common multiple of 189,407,613,924 is 188615196.
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.
189 x 407 x 613 x 924 = 43570110276
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
407 : 1, 11, 37, 407
613 : 1, 613
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,407,613,924, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
407:11x 37
613:613
924:2x 2x 3x 7x 11
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 = 43570110276/(1x231)
LCM = 43570110276/231
LCM = 188615196
Thus, we can understand that the LCM of 189,407,613,924 is 188615196.
