Given numbers are 647,695,139,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,695,139,198 is 89033670.
Find LCM of 647,695,139,198 with Prime Factorization
| 139 | 647, 695, 139, 198 |
| 647, 5, 1, 198 |
Multiply the prime numbers at the bottom and the left side.
139 x 647 x 5 x 1 x 198 = 89033670
Therefore, the lowest common multiple of 647,695,139,198 is 89033670.
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.
647 x 695 x 139 x 198 = 12375680130
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.
647 : 1, 647
695 : 1, 5, 139, 695
139 : 1, 139
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,695,139,198, is 1.
Now, the common factors can be found like this.
647:647
695:5x 139
139:139
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
139 = 139
Therefore, the value for common factors is 139.
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 = 12375680130/(1x139)
LCM = 12375680130/139
LCM = 89033670
Thus, we can understand that the LCM of 647,695,139,198 is 89033670.
