Given numbers are 694,988,998,336,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,988,998,336,744 is 445479727056.
Find LCM of 694,988,998,336,744 with Prime Factorization
| 2 | 694, 988, 998, 336, 744 |
| 2 | 347, 494, 499, 168, 372 |
| 2 | 347, 247, 499, 84, 186 |
| 3 | 347, 247, 499, 42, 93 |
| 347, 247, 499, 14, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 347 x 247 x 499 x 14 x 31 = 445479727056
Therefore, the lowest common multiple of 694,988,998,336,744 is 445479727056.
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.
694 x 988 x 998 x 336 x 744 = 171064215189504
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.
694 : 1, 2, 347, 694
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
998 : 1, 2, 499, 998
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,988,998,336,744, is 2.
Now, the common factors can be found like this.
694:2x 347
988:2x 2x 13x 19
998:2x 499
336:2x 2x 2x 2x 3x 7
744:2x 2x 2x 3x 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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 171064215189504/(2x192)
LCM = 171064215189504/384
LCM = 445479727056
Thus, we can understand that the LCM of 694,988,998,336,744 is 445479727056.
