Given numbers are 207,660,497,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,660,497,636 is 1199569140.
Find LCM of 207,660,497,636 with Prime Factorization
| 2 | 207, 660, 497, 636 |
| 2 | 207, 330, 497, 318 |
| 3 | 207, 165, 497, 159 |
| 69, 55, 497, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 69 x 55 x 497 x 53 = 1199569140
Therefore, the lowest common multiple of 207,660,497,636 is 1199569140.
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.
207 x 660 x 497 x 636 = 43184489040
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.
207 : 1, 3, 9, 23, 69, 207
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
497 : 1, 7, 71, 497
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,660,497,636, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
660:2x 2x 3x 5x 11
497:7x 71
636:2x 2x 3x 53
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 3 = 36
Therefore, the value for common factors is 36.
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 = 43184489040/(1x36)
LCM = 43184489040/36
LCM = 1199569140
Thus, we can understand that the LCM of 207,660,497,636 is 1199569140.
