The LCM of 798,970,300,406,668 is 18743862900.
Find LCM of 798,970,300,406,668 with Prime Factorization
| 2 | 798, 970, 300, 406, 668 |
| 2 | 399, 485, 150, 203, 334 |
| 3 | 399, 485, 75, 203, 167 |
| 5 | 133, 485, 25, 203, 167 |
| 7 | 133, 97, 5, 203, 167 |
| 19, 97, 5, 29, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 19 x 97 x 5 x 29 x 167 = 18743862900
Therefore, the lowest common multiple of 798,970,300,406,668 is 18743862900.
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.
798 x 970 x 300 x 406 x 668 = 62979379344000
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
970 : 1, 2, 5, 10, 97, 194, 485, 970
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
406 : 1, 2, 7, 14, 29, 58, 203, 406
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,970,300,406,668, is 2.
Now, the common factors can be found like this.
798:2x 3x 7x 19
970:2x 5x 97
300:2x 2x 3x 5x 5
406:2x 7x 29
668:2x 2x 167
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 2x 3x 5x 7 = 1680
Therefore, the value for common factors is 1680.
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 = 62979379344000/(2x1680)
LCM = 62979379344000/3360
LCM = 18743862900
Thus, we can understand that the LCM of 798,970,300,406,668 is 18743862900.
