Given numbers are 253,450,972,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,450,972,242 is 67626900.
Find LCM of 253,450,972,242 with Prime Factorization
| 2 | 253, 450, 972, 242 |
| 3 | 253, 225, 486, 121 |
| 3 | 253, 75, 162, 121 |
| 11 | 253, 25, 54, 121 |
| 23, 25, 54, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 23 x 25 x 54 x 11 = 67626900
Therefore, the lowest common multiple of 253,450,972,242 is 67626900.
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 450 x 972 x 242 = 26780252400
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
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,450,972,242, is 1.
Now, the common factors can be found like this.
253:11x 23
450:2x 3x 3x 5x 5
972:2x 2x 3x 3x 3x 3x 3
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 26780252400/(1x396)
LCM = 26780252400/396
LCM = 67626900
Thus, we can understand that the LCM of 253,450,972,242 is 67626900.
