Given numbers are 688,496,884,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,496,884,993 is 4680493584.
Find LCM of 688,496,884,993 with Prime Factorization
2 | 688, 496, 884, 993 |
2 | 344, 248, 442, 993 |
2 | 172, 124, 221, 993 |
2 | 86, 62, 221, 993 |
43, 31, 221, 993 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 31 x 221 x 993 = 4680493584
Therefore, the lowest common multiple of 688,496,884,993 is 4680493584.
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 496 x 884 x 993 = 299551589376
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
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,496,884,993, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
496:2x 2x 2x 2x 31
884:2x 2x 13x 17
993:3x 331
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 299551589376/(1x64)
LCM = 299551589376/64
LCM = 4680493584
Thus, we can understand that the LCM of 688,496,884,993 is 4680493584.
