Given numbers are 401,655,448,262
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,655,448,262 is 117669440.
Find LCM of 401,655,448,262 with Prime Factorization
| 2 | 401, 655, 448, 262 |
| 131 | 401, 655, 224, 131 |
| 401, 5, 224, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 401 x 5 x 224 x 1 = 117669440
Therefore, the lowest common multiple of 401,655,448,262 is 117669440.
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 655 x 448 x 262 = 30829393280
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
655 : 1, 5, 131, 655
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
262 : 1, 2, 131, 262
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,655,448,262, is 1.
Now, the common factors can be found like this.
401:401
655:5x 131
448:2x 2x 2x 2x 2x 2x 7
262:2x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 131 = 262
Therefore, the value for common factors is 262.
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 = 30829393280/(1x262)
LCM = 30829393280/262
LCM = 117669440
Thus, we can understand that the LCM of 401,655,448,262 is 117669440.
