Find LCM of 728,309,875,936 with Prime Factorization
2 | 728, 309, 875, 936 |
2 | 364, 309, 875, 468 |
2 | 182, 309, 875, 234 |
3 | 91, 309, 875, 117 |
7 | 91, 103, 875, 39 |
13 | 13, 103, 125, 39 |
1, 103, 125, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 1 x 103 x 125 x 3 = 84357000
Therefore, the lowest common multiple of 728,309,875,936 is 84357000.
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.
728 x 309 x 875 x 936 = 184235688000
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
309 : 1, 3, 103, 309
875 : 1, 5, 7, 25, 35, 125, 175, 875
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,309,875,936, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
309:3x 103
875:5x 5x 5x 7
936:2x 2x 2x 3x 3x 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 2x 2x 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 184235688000/(1x2184)
LCM = 184235688000/2184
LCM = 84357000
Thus, we can understand that the LCM of 728,309,875,936 is 84357000.
