The LCM of 666,249,645,540,770 is 5490763740.
Find LCM of 666,249,645,540,770 with Prime Factorization
| 2 | 666, 249, 645, 540, 770 |
| 3 | 333, 249, 645, 270, 385 |
| 3 | 111, 83, 215, 90, 385 |
| 5 | 37, 83, 215, 30, 385 |
| 37, 83, 43, 6, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 37 x 83 x 43 x 6 x 77 = 5490763740
Therefore, the lowest common multiple of 666,249,645,540,770 is 5490763740.
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 249 x 645 x 540 x 770 = 44475186294000
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
249 : 1, 3, 83, 249
645 : 1, 3, 5, 15, 43, 129, 215, 645
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,249,645,540,770, is 1.
Now, the common factors can be found like this.
666:2x 3x 3x 37
249:3x 83
645:3x 5x 43
540:2x 2x 3x 3x 3x 5
770:2x 5x 7x 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 3x 3x 3x 5x 5 = 8100
Therefore, the value for common factors is 8100.
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 = 44475186294000/(1x8100)
LCM = 44475186294000/8100
LCM = 5490763740
Thus, we can understand that the LCM of 666,249,645,540,770 is 5490763740.
