Given numbers are 462,627,615,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,627,615,649 is 106169910.
Find LCM of 462,627,615,649 with Prime Factorization
| 3 | 462, 627, 615, 649 |
| 11 | 154, 209, 205, 649 |
| 14, 19, 205, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 14 x 19 x 205 x 59 = 106169910
Therefore, the lowest common multiple of 462,627,615,649 is 106169910.
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.
462 x 627 x 615 x 649 = 115619031990
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
627 : 1, 3, 11, 19, 33, 57, 209, 627
615 : 1, 3, 5, 15, 41, 123, 205, 615
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,627,615,649, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
627:3x 11x 19
615:3x 5x 41
649:11x 59
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 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 115619031990/(1x1089)
LCM = 115619031990/1089
LCM = 106169910
Thus, we can understand that the LCM of 462,627,615,649 is 106169910.
