Given numbers are 626,780,726,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,780,726,105 is 206786580.
Find LCM of 626,780,726,105 with Prime Factorization
2 | 626, 780, 726, 105 |
3 | 313, 390, 363, 105 |
5 | 313, 130, 121, 35 |
313, 26, 121, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 313 x 26 x 121 x 7 = 206786580
Therefore, the lowest common multiple of 626,780,726,105 is 206786580.
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.
626 x 780 x 726 x 105 = 37221584400
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.
626 : 1, 2, 313, 626
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,780,726,105, is 1.
Now, the common factors can be found like this.
626:2x 313
780:2x 2x 3x 5x 13
726:2x 3x 11x 11
105:3x 5x 7
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 37221584400/(1x180)
LCM = 37221584400/180
LCM = 206786580
Thus, we can understand that the LCM of 626,780,726,105 is 206786580.
