Given numbers are 749,643,428,961,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,643,428,961,407 is 753478004356.
Find LCM of 749,643,428,961,407 with Prime Factorization
107 | 749, 643, 428, 961, 407 |
7, 643, 4, 961, 407 |
Multiply the prime numbers at the bottom and the left side.
107 x 7 x 643 x 4 x 961 x 407 = 753478004356
Therefore, the lowest common multiple of 749,643,428,961,407 is 753478004356.
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.
749 x 643 x 428 x 961 x 407 = 80622146466092
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.
749 : 1, 7, 107, 749
643 : 1, 643
428 : 1, 2, 4, 107, 214, 428
961 : 1, 31, 961
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,643,428,961,407, is 1.
Now, the common factors can be found like this.
749:7x 107
643:643
428:2x 2x 107
961:31x 31
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
107 = 107
Therefore, the value for common factors is 107.
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 = 80622146466092/(1x107)
LCM = 80622146466092/107
LCM = 753478004356
Thus, we can understand that the LCM of 749,643,428,961,407 is 753478004356.
