Given numbers are 475,745,975,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,745,975,785 is 433355325.
Find LCM of 475,745,975,785 with Prime Factorization
| 5 | 475, 745, 975, 785 |
| 5 | 95, 149, 195, 157 |
| 19, 149, 39, 157 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 19 x 149 x 39 x 157 = 433355325
Therefore, the lowest common multiple of 475,745,975,785 is 433355325.
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.
475 x 745 x 975 x 785 = 270847078125
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.
475 : 1, 5, 19, 25, 95, 475
745 : 1, 5, 149, 745
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
785 : 1, 5, 157, 785
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,745,975,785, is 5.
Now, the common factors can be found like this.
475:5x 5x 19
745:5x 149
975:3x 5x 5x 13
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 5x 5 = 125
Therefore, the value for common factors is 125.
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 = 270847078125/(5x125)
LCM = 270847078125/625
LCM = 433355325
Thus, we can understand that the LCM of 475,745,975,785 is 433355325.
