Given numbers are 861,327,189,733
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,327,189,733 is 619121853.
Find LCM of 861,327,189,733 with Prime Factorization
| 3 | 861, 327, 189, 733 |
| 7 | 287, 109, 63, 733 |
| 41, 109, 9, 733 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 41 x 109 x 9 x 733 = 619121853
Therefore, the lowest common multiple of 861,327,189,733 is 619121853.
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.
861 x 327 x 189 x 733 = 39004676739
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
327 : 1, 3, 109, 327
189 : 1, 3, 7, 9, 21, 27, 63, 189
733 : 1, 733
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,327,189,733, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
327:3x 109
189:3x 3x 3x 7
733:733
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 39004676739/(1x63)
LCM = 39004676739/63
LCM = 619121853
Thus, we can understand that the LCM of 861,327,189,733 is 619121853.
