Find LCM of 253,855,693,757,615 with Prime Factorization
| 3 | 253, 855, 693, 757, 615 |
| 3 | 253, 285, 231, 757, 205 |
| 5 | 253, 95, 77, 757, 205 |
| 11 | 253, 19, 77, 757, 41 |
| 23, 19, 7, 757, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 23 x 19 x 7 x 757 x 41 = 46996380585
Therefore, the lowest common multiple of 253,855,693,757,615 is 46996380585.
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.
253 x 855 x 693 x 757 x 615 = 69789625168725
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.
253 : 1, 11, 23, 253
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
757 : 1, 757
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,855,693,757,615, is 1.
Now, the common factors can be found like this.
253:11x 23
855:3x 3x 5x 19
693:3x 3x 7x 11
757:757
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 11 = 1485
Therefore, the value for common factors is 1485.
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 = 69789625168725/(1x1485)
LCM = 69789625168725/1485
LCM = 46996380585
Thus, we can understand that the LCM of 253,855,693,757,615 is 46996380585.
