Given numbers are 698,984,808,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,984,808,615 is 173425080.
Find LCM of 698,984,808,615 with Prime Factorization
| 2 | 698, 984, 808, 615 |
| 2 | 349, 492, 404, 615 |
| 2 | 349, 246, 202, 615 |
| 3 | 349, 123, 101, 615 |
| 41 | 349, 41, 101, 205 |
| 349, 1, 101, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 349 x 1 x 101 x 5 = 173425080
Therefore, the lowest common multiple of 698,984,808,615 is 173425080.
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.
698 x 984 x 808 x 615 = 341300557440
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.
698 : 1, 2, 349, 698
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
808 : 1, 2, 4, 8, 101, 202, 404, 808
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,984,808,615, is 1.
Now, the common factors can be found like this.
698:2x 349
984:2x 2x 2x 3x 41
808:2x 2x 2x 101
615:3x 5x 41
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 2x 2x 3x 41 = 1968
Therefore, the value for common factors is 1968.
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 = 341300557440/(1x1968)
LCM = 341300557440/1968
LCM = 173425080
Thus, we can understand that the LCM of 698,984,808,615 is 173425080.
