Find LCM of 405,847,836,620,850 with Prime Factorization
2 | 405, 847, 836, 620, 850 |
2 | 405, 847, 418, 310, 425 |
5 | 405, 847, 209, 155, 425 |
11 | 81, 847, 209, 31, 85 |
81, 77, 19, 31, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 81 x 77 x 19 x 31 x 85 = 68696189100
Therefore, the lowest common multiple of 405,847,836,620,850 is 68696189100.
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.
405 x 847 x 836 x 620 x 850 = 151131616020000
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
847 : 1, 7, 11, 77, 121, 847
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,847,836,620,850, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
847:7x 11x 11
836:2x 2x 11x 19
620:2x 2x 5x 31
850:2x 5x 5x 17
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 2x 5x 5x 11 = 2200
Therefore, the value for common factors is 2200.
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 = 151131616020000/(1x2200)
LCM = 151131616020000/2200
LCM = 68696189100
Thus, we can understand that the LCM of 405,847,836,620,850 is 68696189100.
