Find LCM of 936,653,247,990 with Prime Factorization
| 2 | 936, 653, 247, 990 |
| 3 | 468, 653, 247, 495 |
| 3 | 156, 653, 247, 165 |
| 13 | 52, 653, 247, 55 |
| 4, 653, 19, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 4 x 653 x 19 x 55 = 638712360
Therefore, the lowest common multiple of 936,653,247,990 is 638712360.
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.
936 x 653 x 247 x 990 = 149458692240
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
653 : 1, 653
247 : 1, 13, 19, 247
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,653,247,990, is 1.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
653:653
247:13x 19
990:2x 3x 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 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 149458692240/(1x234)
LCM = 149458692240/234
LCM = 638712360
Thus, we can understand that the LCM of 936,653,247,990 is 638712360.
