Given numbers are 772,284,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,284,938 is 25706828.
Find LCM of 772,284,938 with Prime Factorization
| 2 | 772, 284, 938 |
| 2 | 386, 142, 469 |
| 193, 71, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 193 x 71 x 469 = 25706828
Therefore, the lowest common multiple of 772,284,938 is 25706828.
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.
772 x 284 x 938 = 205654624
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.
772 : 1, 2, 4, 193, 386, 772
284 : 1, 2, 4, 71, 142, 284
938 : 1, 2, 7, 14, 67, 134, 469, 938
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,284,938, is 2.
Now, the common factors can be found like this.
772:2x 2x 193
284:2x 2x 71
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 205654624/(2x4)
LCM = 205654624/8
LCM = 25706828
Thus, we can understand that the LCM of 772,284,938 is 25706828.
