Given numbers are 705,597,685,455,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,597,685,455,406 is 101445350370.
Find LCM of 705,597,685,455,406 with Prime Factorization
| 3 | 705, 597, 685, 455, 406 |
| 5 | 235, 199, 685, 455, 406 |
| 7 | 47, 199, 137, 91, 406 |
| 47, 199, 137, 13, 58 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 47 x 199 x 137 x 13 x 58 = 101445350370
Therefore, the lowest common multiple of 705,597,685,455,406 is 101445350370.
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.
705 x 597 x 685 x 455 x 406 = 53258808944250
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
597 : 1, 3, 199, 597
685 : 1, 5, 137, 685
455 : 1, 5, 7, 13, 35, 65, 91, 455
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,597,685,455,406, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
597:3x 199
685:5x 137
455:5x 7x 13
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 53258808944250/(1x525)
LCM = 53258808944250/525
LCM = 101445350370
Thus, we can understand that the LCM of 705,597,685,455,406 is 101445350370.
