Given numbers are 340,248,765,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,248,765,942 is 29786040.
Find LCM of 340,248,765,942 with Prime Factorization
| 2 | 340, 248, 765, 942 |
| 2 | 170, 124, 765, 471 |
| 3 | 85, 62, 765, 471 |
| 5 | 85, 62, 255, 157 |
| 17 | 17, 62, 51, 157 |
| 1, 62, 3, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 1 x 62 x 3 x 157 = 29786040
Therefore, the lowest common multiple of 340,248,765,942 is 29786040.
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.
340 x 248 x 765 x 942 = 60763521600
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
248 : 1, 2, 4, 8, 31, 62, 124, 248
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,248,765,942, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
248:2x 2x 2x 31
765:3x 3x 5x 17
942:2x 3x 157
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 2x 3x 5x 17 = 2040
Therefore, the value for common factors is 2040.
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 = 60763521600/(1x2040)
LCM = 60763521600/2040
LCM = 29786040
Thus, we can understand that the LCM of 340,248,765,942 is 29786040.
