Find LCM of 575,121,442,975,390 with Prime Factorization
| 2 | 575, 121, 442, 975, 390 |
| 3 | 575, 121, 221, 975, 195 |
| 5 | 575, 121, 221, 325, 65 |
| 5 | 115, 121, 221, 13, 65 |
| 13 | 23, 121, 221, 13, 13 |
| 23, 121, 17, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 13 x 23 x 121 x 17 x 1 x 1 = 92256450
Therefore, the lowest common multiple of 575,121,442,975,390 is 92256450.
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.
575 x 121 x 442 x 975 x 390 = 11693505037500
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.
575 : 1, 5, 23, 25, 115, 575
121 : 1, 11, 121
442 : 1, 2, 13, 17, 26, 34, 221, 442
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 575,121,442,975,390, is 1.
Now, the common factors can be found like this.
575:5x 5x 23
121:11x 11
442:2x 13x 17
975:3x 5x 5x 13
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 5x 13x 13 = 126750
Therefore, the value for common factors is 126750.
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 = 11693505037500/(1x126750)
LCM = 11693505037500/126750
LCM = 92256450
Thus, we can understand that the LCM of 575,121,442,975,390 is 92256450.
