Given numbers are 909,709,341,385,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,709,341,385,620 is 30767522940.
Find LCM of 909,709,341,385,620 with Prime Factorization
| 5 | 909, 709, 341, 385, 620 |
| 11 | 909, 709, 341, 77, 124 |
| 31 | 909, 709, 31, 7, 124 |
| 909, 709, 1, 7, 4 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 31 x 909 x 709 x 1 x 7 x 4 = 30767522940
Therefore, the lowest common multiple of 909,709,341,385,620 is 30767522940.
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.
909 x 709 x 341 x 385 x 620 = 52458626612700
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.
909 : 1, 3, 9, 101, 303, 909
709 : 1, 709
341 : 1, 11, 31, 341
385 : 1, 5, 7, 11, 35, 55, 77, 385
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,709,341,385,620, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
709:709
341:11x 31
385:5x 7x 11
620:2x 2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 31 = 1705
Therefore, the value for common factors is 1705.
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 = 52458626612700/(1x1705)
LCM = 52458626612700/1705
LCM = 30767522940
Thus, we can understand that the LCM of 909,709,341,385,620 is 30767522940.
