Find LCM of 675,575,123,972 with Prime Factorization
| 3 | 675, 575, 123, 972 |
| 3 | 225, 575, 41, 324 |
| 3 | 75, 575, 41, 108 |
| 5 | 25, 575, 41, 36 |
| 5 | 5, 115, 41, 36 |
| 1, 23, 41, 36 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 5 x 1 x 23 x 41 x 36 = 22914900
Therefore, the lowest common multiple of 675,575,123,972 is 22914900.
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.
675 x 575 x 123 x 972 = 46402672500
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
575 : 1, 5, 23, 25, 115, 575
123 : 1, 3, 41, 123
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,575,123,972, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
575:5x 5x 23
123:3x 41
972:2x 2x 3x 3x 3x 3x 3
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 3x 5x 5 = 2025
Therefore, the value for common factors is 2025.
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 = 46402672500/(1x2025)
LCM = 46402672500/2025
LCM = 22914900
Thus, we can understand that the LCM of 675,575,123,972 is 22914900.
