Given numbers are 785,320,442,235
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,320,442,235 is 521842880.
Find LCM of 785,320,442,235 with Prime Factorization
| 2 | 785, 320, 442, 235 |
| 5 | 785, 160, 221, 235 |
| 157, 32, 221, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 157 x 32 x 221 x 47 = 521842880
Therefore, the lowest common multiple of 785,320,442,235 is 521842880.
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.
785 x 320 x 442 x 235 = 26092144000
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.
785 : 1, 5, 157, 785
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
442 : 1, 2, 13, 17, 26, 34, 221, 442
235 : 1, 5, 47, 235
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,320,442,235, is 1.
Now, the common factors can be found like this.
785:5x 157
320:2x 2x 2x 2x 2x 2x 5
442:2x 13x 17
235:5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 26092144000/(1x50)
LCM = 26092144000/50
LCM = 521842880
Thus, we can understand that the LCM of 785,320,442,235 is 521842880.
