Given numbers are 8,191,764,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8,191,764,685 is 1046680.
Find LCM of 8,191,764,685 with Prime Factorization
| 2 | 8, 191, 764, 685 |
| 2 | 4, 191, 382, 685 |
| 191 | 2, 191, 191, 685 |
| 2, 1, 1, 685 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 191 x 2 x 1 x 1 x 685 = 1046680
Therefore, the lowest common multiple of 8,191,764,685 is 1046680.
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.
8 x 191 x 764 x 685 = 799663520
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.
8 : 1, 2, 4, 8
191 : 1, 191
764 : 1, 2, 4, 191, 382, 764
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,191,764,685, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
191:191
764:2x 2x 191
685:5x 137
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 191 = 764
Therefore, the value for common factors is 764.
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 = 799663520/(1x764)
LCM = 799663520/764
LCM = 1046680
Thus, we can understand that the LCM of 8,191,764,685 is 1046680.
