Find LCM of 666,589,740,639 with Prime Factorization
| 2 | 666, 589, 740, 639 |
| 3 | 333, 589, 370, 639 |
| 3 | 111, 589, 370, 213 |
| 37 | 37, 589, 370, 71 |
| 1, 589, 10, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 37 x 1 x 589 x 10 x 71 = 278514540
Therefore, the lowest common multiple of 666,589,740,639 is 278514540.
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.
666 x 589 x 740 x 639 = 185490683640
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.
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
589 : 1, 19, 31, 589
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,589,740,639, is 1.
Now, the common factors can be found like this.
666:2x 3x 3x 37
589:19x 31
740:2x 2x 5x 37
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 37 = 666
Therefore, the value for common factors is 666.
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 = 185490683640/(1x666)
LCM = 185490683640/666
LCM = 278514540
Thus, we can understand that the LCM of 666,589,740,639 is 278514540.
