Given numbers are 401,425,221,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,425,221,842 is 1865472050.
Find LCM of 401,425,221,842 with Prime Factorization
17 | 401, 425, 221, 842 |
401, 25, 13, 842 |
Multiply the prime numbers at the bottom and the left side.
17 x 401 x 25 x 13 x 842 = 1865472050
Therefore, the lowest common multiple of 401,425,221,842 is 1865472050.
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 425 x 221 x 842 = 31713024850
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
425 : 1, 5, 17, 25, 85, 425
221 : 1, 13, 17, 221
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,425,221,842, is 1.
Now, the common factors can be found like this.
401:401
425:5x 5x 17
221:13x 17
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 31713024850/(1x17)
LCM = 31713024850/17
LCM = 1865472050
Thus, we can understand that the LCM of 401,425,221,842 is 1865472050.
