Given numbers are 342,294,641,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,294,641,978 is 1750926114.
Find LCM of 342,294,641,978 with Prime Factorization
| 2 | 342, 294, 641, 978 |
| 3 | 171, 147, 641, 489 |
| 57, 49, 641, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 57 x 49 x 641 x 163 = 1750926114
Therefore, the lowest common multiple of 342,294,641,978 is 1750926114.
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.
342 x 294 x 641 x 978 = 63033340104
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
641 : 1, 641
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,294,641,978, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
294:2x 3x 7x 7
641:641
978:2x 3x 163
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 63033340104/(1x36)
LCM = 63033340104/36
LCM = 1750926114
Thus, we can understand that the LCM of 342,294,641,978 is 1750926114.
