Given numbers are 400,393,428,269
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,393,428,269 is 4524687600.
Find LCM of 400,393,428,269 with Prime Factorization
| 2 | 400, 393, 428, 269 |
| 2 | 200, 393, 214, 269 |
| 100, 393, 107, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 100 x 393 x 107 x 269 = 4524687600
Therefore, the lowest common multiple of 400,393,428,269 is 4524687600.
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.
400 x 393 x 428 x 269 = 18098750400
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
393 : 1, 3, 131, 393
428 : 1, 2, 4, 107, 214, 428
269 : 1, 269
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,393,428,269, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
393:3x 131
428:2x 2x 107
269:269
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 = 18098750400/(1x4)
LCM = 18098750400/4
LCM = 4524687600
Thus, we can understand that the LCM of 400,393,428,269 is 4524687600.
