Given numbers are 901,129,978,698,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,129,978,698,409 is 5408549842614.
Find LCM of 901,129,978,698,409 with Prime Factorization
| 2 | 901, 129, 978, 698, 409 |
| 3 | 901, 129, 489, 349, 409 |
| 901, 43, 163, 349, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 901 x 43 x 163 x 349 x 409 = 5408549842614
Therefore, the lowest common multiple of 901,129,978,698,409 is 5408549842614.
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.
901 x 129 x 978 x 698 x 409 = 32451299055684
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.
901 : 1, 17, 53, 901
129 : 1, 3, 43, 129
978 : 1, 2, 3, 6, 163, 326, 489, 978
698 : 1, 2, 349, 698
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,129,978,698,409, is 1.
Now, the common factors can be found like this.
901:17x 53
129:3x 43
978:2x 3x 163
698:2x 349
409:409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 32451299055684/(1x6)
LCM = 32451299055684/6
LCM = 5408549842614
Thus, we can understand that the LCM of 901,129,978,698,409 is 5408549842614.
