Given numbers are 401,698,681,129,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,698,681,129,774 is 24588759402.
Find LCM of 401,698,681,129,774 with Prime Factorization
2 | 401, 698, 681, 129, 774 |
3 | 401, 349, 681, 129, 387 |
43 | 401, 349, 227, 43, 129 |
401, 349, 227, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 401 x 349 x 227 x 1 x 3 = 24588759402
Therefore, the lowest common multiple of 401,698,681,129,774 is 24588759402.
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 698 x 681 x 129 x 774 = 19031699777148
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
698 : 1, 2, 349, 698
681 : 1, 3, 227, 681
129 : 1, 3, 43, 129
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,698,681,129,774, is 1.
Now, the common factors can be found like this.
401:401
698:2x 349
681:3x 227
129:3x 43
774:2x 3x 3x 43
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 3x 43 = 774
Therefore, the value for common factors is 774.
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 = 19031699777148/(1x774)
LCM = 19031699777148/774
LCM = 24588759402
Thus, we can understand that the LCM of 401,698,681,129,774 is 24588759402.
