Given numbers are 742,476,748,449
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,476,748,449 is 124601092.
Find LCM of 742,476,748,449 with Prime Factorization
2 | 742, 476, 748, 449 |
2 | 371, 238, 374, 449 |
7 | 371, 119, 187, 449 |
17 | 53, 17, 187, 449 |
53, 1, 11, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 53 x 1 x 11 x 449 = 124601092
Therefore, the lowest common multiple of 742,476,748,449 is 124601092.
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.
742 x 476 x 748 x 449 = 118620239584
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,476,748,449, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
476:2x 2x 7x 17
748:2x 2x 11x 17
449:449
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 7x 17 = 952
Therefore, the value for common factors is 952.
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 = 118620239584/(1x952)
LCM = 118620239584/952
LCM = 124601092
Thus, we can understand that the LCM of 742,476,748,449 is 124601092.
