Given numbers are 786,820,875,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,820,875,312 is 1466283000.
Find LCM of 786,820,875,312 with Prime Factorization
| 2 | 786, 820, 875, 312 |
| 2 | 393, 410, 875, 156 |
| 3 | 393, 205, 875, 78 |
| 5 | 131, 205, 875, 26 |
| 131, 41, 175, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 131 x 41 x 175 x 26 = 1466283000
Therefore, the lowest common multiple of 786,820,875,312 is 1466283000.
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.
786 x 820 x 875 x 312 = 175953960000
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
875 : 1, 5, 7, 25, 35, 125, 175, 875
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,820,875,312, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
820:2x 2x 5x 41
875:5x 5x 5x 7
312:2x 2x 2x 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 5 = 120
Therefore, the value for common factors is 120.
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 = 175953960000/(1x120)
LCM = 175953960000/120
LCM = 1466283000
Thus, we can understand that the LCM of 786,820,875,312 is 1466283000.
