Given numbers are 319,770,803,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,770,803,980 is 22821260.
Find LCM of 319,770,803,980 with Prime Factorization
| 2 | 319, 770, 803, 980 |
| 5 | 319, 385, 803, 490 |
| 7 | 319, 77, 803, 98 |
| 11 | 319, 11, 803, 14 |
| 29, 1, 73, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 29 x 1 x 73 x 14 = 22821260
Therefore, the lowest common multiple of 319,770,803,980 is 22821260.
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 770 x 803 x 980 = 193296072200
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
803 : 1, 11, 73, 803
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,770,803,980, is 1.
Now, the common factors can be found like this.
319:11x 29
770:2x 5x 7x 11
803:11x 73
980:2x 2x 5x 7x 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 5x 7x 11x 11 = 8470
Therefore, the value for common factors is 8470.
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 = 193296072200/(1x8470)
LCM = 193296072200/8470
LCM = 22821260
Thus, we can understand that the LCM of 319,770,803,980 is 22821260.
