Given numbers are 705,423,299,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,423,299,634 is 400932090.
Find LCM of 705,423,299,634 with Prime Factorization
| 3 | 705, 423, 299, 634 |
| 47 | 235, 141, 299, 634 |
| 5, 3, 299, 634 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 5 x 3 x 299 x 634 = 400932090
Therefore, the lowest common multiple of 705,423,299,634 is 400932090.
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 423 x 299 x 634 = 56531424690
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
423 : 1, 3, 9, 47, 141, 423
299 : 1, 13, 23, 299
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,423,299,634, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
423:3x 3x 47
299:13x 23
634:2x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 47 = 141
Therefore, the value for common factors is 141.
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 = 56531424690/(1x141)
LCM = 56531424690/141
LCM = 400932090
Thus, we can understand that the LCM of 705,423,299,634 is 400932090.
