Given numbers are 251,285,320,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,285,320,785 is 718783680.
Find LCM of 251,285,320,785 with Prime Factorization
5 | 251, 285, 320, 785 |
251, 57, 64, 157 |
Multiply the prime numbers at the bottom and the left side.
5 x 251 x 57 x 64 x 157 = 718783680
Therefore, the lowest common multiple of 251,285,320,785 is 718783680.
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.
251 x 285 x 320 x 785 = 17969592000
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.
251 : 1, 251
285 : 1, 3, 5, 15, 19, 57, 95, 285
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,285,320,785, is 1.
Now, the common factors can be found like this.
251:251
285:3x 5x 19
320:2x 2x 2x 2x 2x 2x 5
785:5x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 17969592000/(1x25)
LCM = 17969592000/25
LCM = 718783680
Thus, we can understand that the LCM of 251,285,320,785 is 718783680.
