Given numbers are 875,154,121,446
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,154,121,446 is 47220250.
Find LCM of 875,154,121,446 with Prime Factorization
| 2 | 875, 154, 121, 446 |
| 7 | 875, 77, 121, 223 |
| 11 | 125, 11, 121, 223 |
| 125, 1, 11, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 125 x 1 x 11 x 223 = 47220250
Therefore, the lowest common multiple of 875,154,121,446 is 47220250.
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.
875 x 154 x 121 x 446 = 7271918500
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
154 : 1, 2, 7, 11, 14, 22, 77, 154
121 : 1, 11, 121
446 : 1, 2, 223, 446
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,154,121,446, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
154:2x 7x 11
121:11x 11
446:2x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 7271918500/(1x154)
LCM = 7271918500/154
LCM = 47220250
Thus, we can understand that the LCM of 875,154,121,446 is 47220250.
