Given numbers are 319,639,421,900,839
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,639,421,900,839 is 7200051417900.
Find LCM of 319,639,421,900,839 with Prime Factorization
| 3 | 319, 639, 421, 900, 839 |
| 3 | 319, 213, 421, 300, 839 |
| 319, 71, 421, 100, 839 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 319 x 71 x 421 x 100 x 839 = 7200051417900
Therefore, the lowest common multiple of 319,639,421,900,839 is 7200051417900.
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.
319 x 639 x 421 x 900 x 839 = 64800462761100
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.
319 : 1, 11, 29, 319
639 : 1, 3, 9, 71, 213, 639
421 : 1, 421
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
839 : 1, 839
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,639,421,900,839, is 1.
Now, the common factors can be found like this.
319:11x 29
639:3x 3x 71
421:421
900:2x 2x 3x 3x 5x 5
839:839
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 64800462761100/(1x9)
LCM = 64800462761100/9
LCM = 7200051417900
Thus, we can understand that the LCM of 319,639,421,900,839 is 7200051417900.
