Find LCM of 666,643,550,995,660 with Prime Factorization
2 | 666, 643, 550, 995, 660 |
3 | 333, 643, 275, 995, 330 |
5 | 111, 643, 275, 995, 110 |
11 | 111, 643, 55, 199, 22 |
111, 643, 5, 199, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 111 x 643 x 5 x 199 x 2 = 46870649100
Therefore, the lowest common multiple of 666,643,550,995,660 is 46870649100.
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 643 x 550 x 995 x 660 = 154673142030000
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
643 : 1, 643
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
995 : 1, 5, 199, 995
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,643,550,995,660, is 1.
Now, the common factors can be found like this.
666:2x 3x 3x 37
643:643
550:2x 5x 5x 11
995:5x 199
660:2x 2x 3x 5x 11
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 3x 5x 5x 11 = 3300
Therefore, the value for common factors is 3300.
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 = 154673142030000/(1x3300)
LCM = 154673142030000/3300
LCM = 46870649100
Thus, we can understand that the LCM of 666,643,550,995,660 is 46870649100.
