Given numbers are 987,556,334,132,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,556,334,132,820 is 206659303620.
Find LCM of 987,556,334,132,820 with Prime Factorization
| 2 | 987, 556, 334, 132, 820 |
| 2 | 987, 278, 167, 66, 410 |
| 3 | 987, 139, 167, 33, 205 |
| 329, 139, 167, 11, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 329 x 139 x 167 x 11 x 205 = 206659303620
Therefore, the lowest common multiple of 987,556,334,132,820 is 206659303620.
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 556 x 334 x 132 x 820 = 19839293147520
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
556 : 1, 2, 4, 139, 278, 556
334 : 1, 2, 167, 334
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,556,334,132,820, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
556:2x 2x 139
334:2x 167
132:2x 2x 3x 11
820:2x 2x 5x 41
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 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 19839293147520/(1x96)
LCM = 19839293147520/96
LCM = 206659303620
Thus, we can understand that the LCM of 987,556,334,132,820 is 206659303620.
