Given numbers are 189,714,631,591
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,714,631,591 is 798796782.
Find LCM of 189,714,631,591 with Prime Factorization
| 3 | 189, 714, 631, 591 |
| 7 | 63, 238, 631, 197 |
| 9, 34, 631, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 9 x 34 x 631 x 197 = 798796782
Therefore, the lowest common multiple of 189,714,631,591 is 798796782.
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 714 x 631 x 591 = 50324197266
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
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
631 : 1, 631
591 : 1, 3, 197, 591
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,714,631,591, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
714:2x 3x 7x 17
631:631
591:3x 197
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 = 50324197266/(1x63)
LCM = 50324197266/63
LCM = 798796782
Thus, we can understand that the LCM of 189,714,631,591 is 798796782.
