Given numbers are 647,740,888,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,740,888,667 is 1916077560.
Find LCM of 647,740,888,667 with Prime Factorization
| 2 | 647, 740, 888, 667 |
| 2 | 647, 370, 444, 667 |
| 37 | 647, 185, 222, 667 |
| 647, 5, 6, 667 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 647 x 5 x 6 x 667 = 1916077560
Therefore, the lowest common multiple of 647,740,888,667 is 1916077560.
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 740 x 888 x 667 = 283579478880
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,740,888,667, is 1.
Now, the common factors can be found like this.
647:647
740:2x 2x 5x 37
888:2x 2x 2x 3x 37
667:23x 29
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 37 = 148
Therefore, the value for common factors is 148.
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 = 283579478880/(1x148)
LCM = 283579478880/148
LCM = 1916077560
Thus, we can understand that the LCM of 647,740,888,667 is 1916077560.
