Given numbers are 987,579,423,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,579,423,880 is 502896240.
Find LCM of 987,579,423,880 with Prime Factorization
3 | 987, 579, 423, 880 |
47 | 329, 193, 141, 880 |
7, 193, 3, 880 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 7 x 193 x 3 x 880 = 502896240
Therefore, the lowest common multiple of 987,579,423,880 is 502896240.
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 579 x 423 x 880 = 212725109520
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
579 : 1, 3, 193, 579
423 : 1, 3, 9, 47, 141, 423
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,579,423,880, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
579:3x 193
423:3x 3x 47
880:2x 2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 47 = 423
Therefore, the value for common factors is 423.
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 = 212725109520/(1x423)
LCM = 212725109520/423
LCM = 502896240
Thus, we can understand that the LCM of 987,579,423,880 is 502896240.
