Given numbers are 437,645,805,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,645,805,785 is 309769635.
Find LCM of 437,645,805,785 with Prime Factorization
| 5 | 437, 645, 805, 785 |
| 23 | 437, 129, 161, 157 |
| 19, 129, 7, 157 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 19 x 129 x 7 x 157 = 309769635
Therefore, the lowest common multiple of 437,645,805,785 is 309769635.
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.
437 x 645 x 805 x 785 = 178117540125
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.
437 : 1, 19, 23, 437
645 : 1, 3, 5, 15, 43, 129, 215, 645
805 : 1, 5, 7, 23, 35, 115, 161, 805
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,645,805,785, is 1.
Now, the common factors can be found like this.
437:19x 23
645:3x 5x 43
805:5x 7x 23
785:5x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 23 = 575
Therefore, the value for common factors is 575.
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 = 178117540125/(1x575)
LCM = 178117540125/575
LCM = 309769635
Thus, we can understand that the LCM of 437,645,805,785 is 309769635.
