Given numbers are 639,678,836,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,678,836,290 is 8752932540.
Find LCM of 639,678,836,290 with Prime Factorization
2 | 639, 678, 836, 290 |
3 | 639, 339, 418, 145 |
213, 113, 418, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 213 x 113 x 418 x 145 = 8752932540
Therefore, the lowest common multiple of 639,678,836,290 is 8752932540.
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.
639 x 678 x 836 x 290 = 105035190480
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.
639 : 1, 3, 9, 71, 213, 639
678 : 1, 2, 3, 6, 113, 226, 339, 678
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,678,836,290, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
678:2x 3x 113
836:2x 2x 11x 19
290:2x 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.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 105035190480/(1x12)
LCM = 105035190480/12
LCM = 8752932540
Thus, we can understand that the LCM of 639,678,836,290 is 8752932540.
