Given numbers are 401,126,481,609,446
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,126,481,609,446 is 157167539802.
Find LCM of 401,126,481,609,446 with Prime Factorization
| 2 | 401, 126, 481, 609, 446 |
| 3 | 401, 63, 481, 609, 223 |
| 7 | 401, 21, 481, 203, 223 |
| 401, 3, 481, 29, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 401 x 3 x 481 x 29 x 223 = 157167539802
Therefore, the lowest common multiple of 401,126,481,609,446 is 157167539802.
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.
401 x 126 x 481 x 609 x 446 = 6601036671684
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.
401 : 1, 401
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
481 : 1, 13, 37, 481
609 : 1, 3, 7, 21, 29, 87, 203, 609
446 : 1, 2, 223, 446
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,126,481,609,446, is 1.
Now, the common factors can be found like this.
401:401
126:2x 3x 3x 7
481:13x 37
609:3x 7x 29
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 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 6601036671684/(1x42)
LCM = 6601036671684/42
LCM = 157167539802
Thus, we can understand that the LCM of 401,126,481,609,446 is 157167539802.
