Given numbers are 909,290,867,430,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,290,867,430,978 is 533968679610.
Find LCM of 909,290,867,430,978 with Prime Factorization
| 2 | 909, 290, 867, 430, 978 |
| 3 | 909, 145, 867, 215, 489 |
| 5 | 303, 145, 289, 215, 163 |
| 303, 29, 289, 43, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 303 x 29 x 289 x 43 x 163 = 533968679610
Therefore, the lowest common multiple of 909,290,867,430,978 is 533968679610.
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.
909 x 290 x 867 x 430 x 978 = 96114362329800
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.
909 : 1, 3, 9, 101, 303, 909
290 : 1, 2, 5, 10, 29, 58, 145, 290
867 : 1, 3, 17, 51, 289, 867
430 : 1, 2, 5, 10, 43, 86, 215, 430
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,290,867,430,978, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
290:2x 5x 29
867:3x 17x 17
430:2x 5x 43
978:2x 3x 163
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 = 96114362329800/(1x180)
LCM = 96114362329800/180
LCM = 533968679610
Thus, we can understand that the LCM of 909,290,867,430,978 is 533968679610.
