Find LCM of 216,621,631,666,775 with Prime Factorization
| 2 | 216, 621, 631, 666, 775 |
| 3 | 108, 621, 631, 333, 775 |
| 3 | 36, 207, 631, 111, 775 |
| 3 | 12, 69, 631, 37, 775 |
| 4, 23, 631, 37, 775 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 4 x 23 x 631 x 37 x 775 = 89890619400
Therefore, the lowest common multiple of 216,621,631,666,775 is 89890619400.
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.
216 x 621 x 631 x 666 x 775 = 43686841028400
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
621 : 1, 3, 9, 23, 27, 69, 207, 621
631 : 1, 631
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,621,631,666,775, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
621:3x 3x 3x 23
631:631
666:2x 3x 3x 37
775:5x 5x 31
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 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 43686841028400/(1x486)
LCM = 43686841028400/486
LCM = 89890619400
Thus, we can understand that the LCM of 216,621,631,666,775 is 89890619400.
