Given numbers are 310,802,978,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,802,978,743 is 45165179370.
Find LCM of 310,802,978,743 with Prime Factorization
| 2 | 310, 802, 978, 743 |
| 155, 401, 489, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 155 x 401 x 489 x 743 = 45165179370
Therefore, the lowest common multiple of 310,802,978,743 is 45165179370.
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.
310 x 802 x 978 x 743 = 180660717480
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
802 : 1, 2, 401, 802
978 : 1, 2, 3, 6, 163, 326, 489, 978
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,802,978,743, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
802:2x 401
978:2x 3x 163
743:743
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 180660717480/(1x4)
LCM = 180660717480/4
LCM = 45165179370
Thus, we can understand that the LCM of 310,802,978,743 is 45165179370.
