Given numbers are 987,909,842,371,608
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,909,842,371,608 is 4057152440544.
Find LCM of 987,909,842,371,608 with Prime Factorization
| 2 | 987, 909, 842, 371, 608 |
| 3 | 987, 909, 421, 371, 304 |
| 7 | 329, 303, 421, 371, 304 |
| 47, 303, 421, 53, 304 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 303 x 421 x 53 x 304 = 4057152440544
Therefore, the lowest common multiple of 987,909,842,371,608 is 4057152440544.
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.
987 x 909 x 842 x 371 x 608 = 170400402502848
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
909 : 1, 3, 9, 101, 303, 909
842 : 1, 2, 421, 842
371 : 1, 7, 53, 371
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,909,842,371,608, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
909:3x 3x 101
842:2x 421
371:7x 53
608:2x 2x 2x 2x 2x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 170400402502848/(1x42)
LCM = 170400402502848/42
LCM = 4057152440544
Thus, we can understand that the LCM of 987,909,842,371,608 is 4057152440544.
