Given numbers are 407,978,980,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,978,980,313 is 61048315020.
Find LCM of 407,978,980,313 with Prime Factorization
| 2 | 407, 978, 980, 313 |
| 407, 489, 490, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 407 x 489 x 490 x 313 = 61048315020
Therefore, the lowest common multiple of 407,978,980,313 is 61048315020.
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.
407 x 978 x 980 x 313 = 122096630040
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.
407 : 1, 11, 37, 407
978 : 1, 2, 3, 6, 163, 326, 489, 978
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,978,980,313, is 1.
Now, the common factors can be found like this.
407:11x 37
978:2x 3x 163
980:2x 2x 5x 7x 7
313:313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 122096630040/(1x2)
LCM = 122096630040/2
LCM = 61048315020
Thus, we can understand that the LCM of 407,978,980,313 is 61048315020.
