Given numbers are 673,440,605,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 673,440,605,924 is 68403720.
Find LCM of 673,440,605,924 with Prime Factorization
| 2 | 673, 440, 605, 924 |
| 2 | 673, 220, 605, 462 |
| 5 | 673, 110, 605, 231 |
| 11 | 673, 22, 121, 231 |
| 673, 2, 11, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 673 x 2 x 11 x 21 = 68403720
Therefore, the lowest common multiple of 673,440,605,924 is 68403720.
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.
673 x 440 x 605 x 924 = 165537002400
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.
673 : 1, 673
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
605 : 1, 5, 11, 55, 121, 605
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,440,605,924, is 1.
Now, the common factors can be found like this.
673:673
440:2x 2x 2x 5x 11
605:5x 11x 11
924:2x 2x 3x 7x 11
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 5x 11x 11 = 2420
Therefore, the value for common factors is 2420.
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 = 165537002400/(1x2420)
LCM = 165537002400/2420
LCM = 68403720
Thus, we can understand that the LCM of 673,440,605,924 is 68403720.
