Given numbers are 688,973,331,423,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,973,331,423,666 is 3467938312944.
Find LCM of 688,973,331,423,666 with Prime Factorization
| 2 | 688, 973, 331, 423, 666 |
| 3 | 344, 973, 331, 423, 333 |
| 3 | 344, 973, 331, 141, 111 |
| 344, 973, 331, 47, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 344 x 973 x 331 x 47 x 37 = 3467938312944
Therefore, the lowest common multiple of 688,973,331,423,666 is 3467938312944.
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.
688 x 973 x 331 x 423 x 666 = 62422889632992
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
973 : 1, 7, 139, 973
331 : 1, 331
423 : 1, 3, 9, 47, 141, 423
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,973,331,423,666, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
973:7x 139
331:331
423:3x 3x 47
666:2x 3x 3x 37
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 3 = 18
Therefore, the value for common factors is 18.
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 = 62422889632992/(1x18)
LCM = 62422889632992/18
LCM = 3467938312944
Thus, we can understand that the LCM of 688,973,331,423,666 is 3467938312944.
