Given numbers are 639,571,146,970,159
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,571,146,970,159 is 1369327816170.
Find LCM of 639,571,146,970,159 with Prime Factorization
| 2 | 639, 571, 146, 970, 159 |
| 3 | 639, 571, 73, 485, 159 |
| 213, 571, 73, 485, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 213 x 571 x 73 x 485 x 53 = 1369327816170
Therefore, the lowest common multiple of 639,571,146,970,159 is 1369327816170.
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 571 x 146 x 970 x 159 = 8215966897020
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
571 : 1, 571
146 : 1, 2, 73, 146
970 : 1, 2, 5, 10, 97, 194, 485, 970
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,571,146,970,159, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
571:571
146:2x 73
970:2x 5x 97
159:3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 8215966897020/(1x6)
LCM = 8215966897020/6
LCM = 1369327816170
Thus, we can understand that the LCM of 639,571,146,970,159 is 1369327816170.
