Given numbers are 978,152,514,627,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,152,514,627,742 is 77956469976.
Find LCM of 978,152,514,627,742 with Prime Factorization
| 2 | 978, 152, 514, 627, 742 |
| 3 | 489, 76, 257, 627, 371 |
| 19 | 163, 76, 257, 209, 371 |
| 163, 4, 257, 11, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 163 x 4 x 257 x 11 x 371 = 77956469976
Therefore, the lowest common multiple of 978,152,514,627,742 is 77956469976.
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.
978 x 152 x 514 x 627 x 742 = 35548150309056
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
152 : 1, 2, 4, 8, 19, 38, 76, 152
514 : 1, 2, 257, 514
627 : 1, 3, 11, 19, 33, 57, 209, 627
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,152,514,627,742, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
152:2x 2x 2x 19
514:2x 257
627:3x 11x 19
742:2x 7x 53
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 2x 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 35548150309056/(1x456)
LCM = 35548150309056/456
LCM = 77956469976
Thus, we can understand that the LCM of 978,152,514,627,742 is 77956469976.
