Given numbers are 786,870,254,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,870,254,870 is 14474190.
Find LCM of 786,870,254,870 with Prime Factorization
| 2 | 786, 870, 254, 870 |
| 3 | 393, 435, 127, 435 |
| 5 | 131, 145, 127, 145 |
| 29 | 131, 29, 127, 29 |
| 131, 1, 127, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 131 x 1 x 127 x 1 = 14474190
Therefore, the lowest common multiple of 786,870,254,870 is 14474190.
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 870 x 254 x 870 = 151110543600
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
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
254 : 1, 2, 127, 254
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,870,254,870, is 2.
Now, the common factors can be found like this.
786:2x 3x 131
870:2x 3x 5x 29
254:2x 127
870:2x 3x 5x 29
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 3x 3x 5x 29 = 5220
Therefore, the value for common factors is 5220.
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 = 151110543600/(2x5220)
LCM = 151110543600/10440
LCM = 14474190
Thus, we can understand that the LCM of 786,870,254,870 is 14474190.
