Given numbers are 769,195,478,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,195,478,243 is 5805957690.
Find LCM of 769,195,478,243 with Prime Factorization
| 3 | 769, 195, 478, 243 |
| 769, 65, 478, 81 |
Multiply the prime numbers at the bottom and the left side.
3 x 769 x 65 x 478 x 81 = 5805957690
Therefore, the lowest common multiple of 769,195,478,243 is 5805957690.
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.
769 x 195 x 478 x 243 = 17417873070
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.
769 : 1, 769
195 : 1, 3, 5, 13, 15, 39, 65, 195
478 : 1, 2, 239, 478
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,195,478,243, is 1.
Now, the common factors can be found like this.
769:769
195:3x 5x 13
478:2x 239
243:3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 17417873070/(1x3)
LCM = 17417873070/3
LCM = 5805957690
Thus, we can understand that the LCM of 769,195,478,243 is 5805957690.
