Given numbers are 401,884,636,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,884,636,374 is 619992516.
Find LCM of 401,884,636,374 with Prime Factorization
| 2 | 401, 884, 636, 374 |
| 2 | 401, 442, 318, 187 |
| 17 | 401, 221, 159, 187 |
| 401, 13, 159, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 401 x 13 x 159 x 11 = 619992516
Therefore, the lowest common multiple of 401,884,636,374 is 619992516.
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 884 x 636 x 374 = 84318982176
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
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,884,636,374, is 1.
Now, the common factors can be found like this.
401:401
884:2x 2x 13x 17
636:2x 2x 3x 53
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 84318982176/(1x136)
LCM = 84318982176/136
LCM = 619992516
Thus, we can understand that the LCM of 401,884,636,374 is 619992516.
