Given numbers are 774,642,454,292
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,642,454,292 is 2744754156.
Find LCM of 774,642,454,292 with Prime Factorization
| 2 | 774, 642, 454, 292 |
| 3 | 387, 321, 227, 146 |
| 129, 107, 227, 146 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 129 x 107 x 227 x 146 = 2744754156
Therefore, the lowest common multiple of 774,642,454,292 is 2744754156.
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.
774 x 642 x 454 x 292 = 65874099744
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
642 : 1, 2, 3, 6, 107, 214, 321, 642
454 : 1, 2, 227, 454
292 : 1, 2, 4, 73, 146, 292
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,642,454,292, is 2.
Now, the common factors can be found like this.
774:2x 3x 3x 43
642:2x 3x 107
454:2x 227
292:2x 2x 73
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 3 = 12
Therefore, the value for common factors is 12.
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 = 65874099744/(2x12)
LCM = 65874099744/24
LCM = 2744754156
Thus, we can understand that the LCM of 774,642,454,292 is 2744754156.
