Given numbers are 654,261,763,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,261,763,145 is 1991430.
Find LCM of 654,261,763,145 with Prime Factorization
| 3 | 654, 261, 763, 145 |
| 29 | 218, 87, 763, 145 |
| 109 | 218, 3, 763, 5 |
| 2, 3, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 109 x 2 x 3 x 7 x 5 = 1991430
Therefore, the lowest common multiple of 654,261,763,145 is 1991430.
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.
654 x 261 x 763 x 145 = 18884730690
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
261 : 1, 3, 9, 29, 87, 261
763 : 1, 7, 109, 763
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,261,763,145, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
261:3x 3x 29
763:7x 109
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 29x 109 = 9483
Therefore, the value for common factors is 9483.
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 = 18884730690/(1x9483)
LCM = 18884730690/9483
LCM = 1991430
Thus, we can understand that the LCM of 654,261,763,145 is 1991430.
