Given numbers are 874,479,688,666,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,479,688,666,868 is 10406611840464.
Find LCM of 874,479,688,666,868 with Prime Factorization
| 2 | 874, 479, 688, 666, 868 |
| 2 | 437, 479, 344, 333, 434 |
| 437, 479, 172, 333, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 437 x 479 x 172 x 333 x 217 = 10406611840464
Therefore, the lowest common multiple of 874,479,688,666,868 is 10406611840464.
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.
874 x 479 x 688 x 666 x 868 = 166505789447424
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
479 : 1, 479
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,479,688,666,868, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
479:479
688:2x 2x 2x 2x 43
666:2x 3x 3x 37
868:2x 2x 7x 31
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 2 = 16
Therefore, the value for common factors is 16.
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 = 166505789447424/(1x16)
LCM = 166505789447424/16
LCM = 10406611840464
Thus, we can understand that the LCM of 874,479,688,666,868 is 10406611840464.
