Given numbers are 649,977,177,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,977,177,678 is 429901494.
Find LCM of 649,977,177,678 with Prime Factorization
| 3 | 649, 977, 177, 678 |
| 59 | 649, 977, 59, 226 |
| 11, 977, 1, 226 |
Multiply the prime numbers at the bottom and the left side.
3 x 59 x 11 x 977 x 1 x 226 = 429901494
Therefore, the lowest common multiple of 649,977,177,678 is 429901494.
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.
649 x 977 x 177 x 678 = 76092564438
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.
649 : 1, 11, 59, 649
977 : 1, 977
177 : 1, 3, 59, 177
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,977,177,678, is 1.
Now, the common factors can be found like this.
649:11x 59
977:977
177:3x 59
678:2x 3x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 59 = 177
Therefore, the value for common factors is 177.
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 = 76092564438/(1x177)
LCM = 76092564438/177
LCM = 429901494
Thus, we can understand that the LCM of 649,977,177,678 is 429901494.
