Given numbers are 478,987,770,740,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,987,770,740,609 is 55684901580.
Find LCM of 478,987,770,740,609 with Prime Factorization
| 2 | 478, 987, 770, 740, 609 |
| 3 | 239, 987, 385, 370, 609 |
| 5 | 239, 329, 385, 370, 203 |
| 7 | 239, 329, 77, 74, 203 |
| 239, 47, 11, 74, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 239 x 47 x 11 x 74 x 29 = 55684901580
Therefore, the lowest common multiple of 478,987,770,740,609 is 55684901580.
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.
478 x 987 x 770 x 740 x 609 = 163713610645200
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.
478 : 1, 2, 239, 478
987 : 1, 3, 7, 21, 47, 141, 329, 987
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,987,770,740,609, is 1.
Now, the common factors can be found like this.
478:2x 239
987:3x 7x 47
770:2x 5x 7x 11
740:2x 2x 5x 37
609:3x 7x 29
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 5x 7x 7 = 2940
Therefore, the value for common factors is 2940.
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 = 163713610645200/(1x2940)
LCM = 163713610645200/2940
LCM = 55684901580
Thus, we can understand that the LCM of 478,987,770,740,609 is 55684901580.
