The LCM of 436,855,630,845 is 440998740.
Find LCM of 436,855,630,845 with Prime Factorization
2 | 436, 855, 630, 845 |
3 | 218, 855, 315, 845 |
3 | 218, 285, 105, 845 |
5 | 218, 95, 35, 845 |
218, 19, 7, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 218 x 19 x 7 x 169 = 440998740
Therefore, the lowest common multiple of 436,855,630,845 is 440998740.
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.
436 x 855 x 630 x 845 = 198449433000
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.
436 : 1, 2, 4, 109, 218, 436
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,855,630,845, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
855:3x 3x 5x 19
630:2x 3x 3x 5x 7
845:5x 13x 13
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 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 198449433000/(1x450)
LCM = 198449433000/450
LCM = 440998740
Thus, we can understand that the LCM of 436,855,630,845 is 440998740.
