Given numbers are 220,782,935,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,782,935,780 is 3354780.
Find LCM of 220,782,935,780 with Prime Factorization
| 2 | 220, 782, 935, 780 |
| 2 | 110, 391, 935, 390 |
| 5 | 55, 391, 935, 195 |
| 11 | 11, 391, 187, 39 |
| 17 | 1, 391, 17, 39 |
| 1, 23, 1, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 17 x 1 x 23 x 1 x 39 = 3354780
Therefore, the lowest common multiple of 220,782,935,780 is 3354780.
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.
220 x 782 x 935 x 780 = 125468772000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
782 : 1, 2, 17, 23, 34, 46, 391, 782
935 : 1, 5, 11, 17, 55, 85, 187, 935
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,782,935,780, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
782:2x 17x 23
935:5x 11x 17
780:2x 2x 3x 5x 13
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 2x 5x 5x 11x 17 = 37400
Therefore, the value for common factors is 37400.
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 = 125468772000/(1x37400)
LCM = 125468772000/37400
LCM = 3354780
Thus, we can understand that the LCM of 220,782,935,780 is 3354780.
