The LCM of 475,242,975,561 is 76211850.
Find LCM of 475,242,975,561 with Prime Factorization
| 3 | 475, 242, 975, 561 |
| 5 | 475, 242, 325, 187 |
| 5 | 95, 242, 65, 187 |
| 11 | 19, 242, 13, 187 |
| 19, 22, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 11 x 19 x 22 x 13 x 17 = 76211850
Therefore, the lowest common multiple of 475,242,975,561 is 76211850.
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 242 x 975 x 561 = 62874776250
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
242 : 1, 2, 11, 22, 121, 242
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,242,975,561, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
242:2x 11x 11
975:3x 5x 5x 13
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11 = 825
Therefore, the value for common factors is 825.
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 = 62874776250/(1x825)
LCM = 62874776250/825
LCM = 76211850
Thus, we can understand that the LCM of 475,242,975,561 is 76211850.
