Given numbers are 565,385,692,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,385,692,642 is 9663852660.
Find LCM of 565,385,692,642 with Prime Factorization
| 2 | 565, 385, 692, 642 |
| 5 | 565, 385, 346, 321 |
| 113, 77, 346, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 113 x 77 x 346 x 321 = 9663852660
Therefore, the lowest common multiple of 565,385,692,642 is 9663852660.
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.
565 x 385 x 692 x 642 = 96638526600
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.
565 : 1, 5, 113, 565
385 : 1, 5, 7, 11, 35, 55, 77, 385
692 : 1, 2, 4, 173, 346, 692
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,385,692,642, is 1.
Now, the common factors can be found like this.
565:5x 113
385:5x 7x 11
692:2x 2x 173
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 96638526600/(1x10)
LCM = 96638526600/10
LCM = 9663852660
Thus, we can understand that the LCM of 565,385,692,642 is 9663852660.
