Given numbers are 987,880,500,238
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,880,500,238 is 369138000.
Find LCM of 987,880,500,238 with Prime Factorization
2 | 987, 880, 500, 238 |
2 | 987, 440, 250, 119 |
5 | 987, 220, 125, 119 |
7 | 987, 44, 25, 119 |
141, 44, 25, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 141 x 44 x 25 x 17 = 369138000
Therefore, the lowest common multiple of 987,880,500,238 is 369138000.
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 880 x 500 x 238 = 103358640000
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
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,880,500,238, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
880:2x 2x 2x 2x 5x 11
500:2x 2x 5x 5x 5
238:2x 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 2x 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 103358640000/(1x280)
LCM = 103358640000/280
LCM = 369138000
Thus, we can understand that the LCM of 987,880,500,238 is 369138000.
