Given numbers are 786,676,546,416
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,676,546,416 is 14877408.
Find LCM of 786,676,546,416 with Prime Factorization
| 2 | 786, 676, 546, 416 |
| 2 | 393, 338, 273, 208 |
| 3 | 393, 169, 273, 104 |
| 13 | 131, 169, 91, 104 |
| 131, 13, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 131 x 13 x 7 x 8 = 14877408
Therefore, the lowest common multiple of 786,676,546,416 is 14877408.
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 676 x 546 x 416 = 120685533696
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,676,546,416, is 2.
Now, the common factors can be found like this.
786:2x 3x 131
676:2x 2x 13x 13
546:2x 3x 7x 13
416:2x 2x 2x 2x 2x 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 13x 13 = 4056
Therefore, the value for common factors is 4056.
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 = 120685533696/(2x4056)
LCM = 120685533696/8112
LCM = 14877408
Thus, we can understand that the LCM of 786,676,546,416 is 14877408.
