Given numbers are 711,990,936,653
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,990,936,653 is 2655698760.
Find LCM of 711,990,936,653 with Prime Factorization
| 2 | 711, 990, 936, 653 |
| 3 | 711, 495, 468, 653 |
| 3 | 237, 165, 156, 653 |
| 79, 55, 52, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 79 x 55 x 52 x 653 = 2655698760
Therefore, the lowest common multiple of 711,990,936,653 is 2655698760.
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.
711 x 990 x 936 x 653 = 430223199120
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.
711 : 1, 3, 9, 79, 237, 711
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
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,990,936,653, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
990:2x 3x 3x 5x 11
936:2x 2x 2x 3x 3x 13
653:653
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 3 = 162
Therefore, the value for common factors is 162.
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 = 430223199120/(1x162)
LCM = 430223199120/162
LCM = 2655698760
Thus, we can understand that the LCM of 711,990,936,653 is 2655698760.
