Given numbers are 711,945,493,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,945,493,663 is 478463895.
Find LCM of 711,945,493,663 with Prime Factorization
| 3 | 711, 945, 493, 663 |
| 3 | 237, 315, 493, 221 |
| 17 | 79, 105, 493, 221 |
| 79, 105, 29, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 79 x 105 x 29 x 13 = 478463895
Therefore, the lowest common multiple of 711,945,493,663 is 478463895.
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.
711 x 945 x 493 x 663 = 219614927805
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.
711 : 1, 3, 9, 79, 237, 711
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
493 : 1, 17, 29, 493
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,945,493,663, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
945:3x 3x 3x 5x 7
493:17x 29
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 219614927805/(1x459)
LCM = 219614927805/459
LCM = 478463895
Thus, we can understand that the LCM of 711,945,493,663 is 478463895.
