Given numbers are 649,798,997,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,798,997,178 is 45954998166.
Find LCM of 649,798,997,178 with Prime Factorization
| 2 | 649, 798, 997, 178 |
| 649, 399, 997, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 649 x 399 x 997 x 89 = 45954998166
Therefore, the lowest common multiple of 649,798,997,178 is 45954998166.
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 798 x 997 x 178 = 91909996332
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
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
997 : 1, 997
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,798,997,178, is 1.
Now, the common factors can be found like this.
649:11x 59
798:2x 3x 7x 19
997:997
178:2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 91909996332/(1x2)
LCM = 91909996332/2
LCM = 45954998166
Thus, we can understand that the LCM of 649,798,997,178 is 45954998166.
