Given numbers are 706,915,285,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,915,285,342 is 36821430.
Find LCM of 706,915,285,342 with Prime Factorization
| 2 | 706, 915, 285, 342 |
| 3 | 353, 915, 285, 171 |
| 5 | 353, 305, 95, 57 |
| 19 | 353, 61, 19, 57 |
| 353, 61, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 353 x 61 x 1 x 3 = 36821430
Therefore, the lowest common multiple of 706,915,285,342 is 36821430.
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.
706 x 915 x 285 x 342 = 62964645300
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.
706 : 1, 2, 353, 706
915 : 1, 3, 5, 15, 61, 183, 305, 915
285 : 1, 3, 5, 15, 19, 57, 95, 285
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,915,285,342, is 1.
Now, the common factors can be found like this.
706:2x 353
915:3x 5x 61
285:3x 5x 19
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 19 = 1710
Therefore, the value for common factors is 1710.
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 = 62964645300/(1x1710)
LCM = 62964645300/1710
LCM = 36821430
Thus, we can understand that the LCM of 706,915,285,342 is 36821430.
