Find LCM of 987,400,361,950,357 with Prime Factorization
| 2 | 987, 400, 361, 950, 357 |
| 3 | 987, 200, 361, 475, 357 |
| 5 | 329, 200, 361, 475, 119 |
| 5 | 329, 40, 361, 95, 119 |
| 7 | 329, 8, 361, 19, 119 |
| 19 | 47, 8, 361, 19, 17 |
| 47, 8, 1, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 7 x 19 x 47 x 8 x 1 x 19 x 17 = 2422887600
Therefore, the lowest common multiple of 987,400,361,950,357 is 2422887600.
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 400 x 361 x 950 x 357 = 48336607620000
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
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
361 : 1, 19, 361
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,400,361,950,357, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
400:2x 2x 2x 2x 5x 5
361:19x 19
950:2x 5x 5x 19
357:3x 7x 17
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 5x 5x 7x 19 = 19950
Therefore, the value for common factors is 19950.
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 = 48336607620000/(1x19950)
LCM = 48336607620000/19950
LCM = 2422887600
Thus, we can understand that the LCM of 987,400,361,950,357 is 2422887600.
