Given numbers are 824,490,742,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,490,742,655 is 1401652840.
Find LCM of 824,490,742,655 with Prime Factorization
2 | 824, 490, 742, 655 |
5 | 412, 245, 371, 655 |
7 | 412, 49, 371, 131 |
412, 7, 53, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 412 x 7 x 53 x 131 = 1401652840
Therefore, the lowest common multiple of 824,490,742,655 is 1401652840.
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.
824 x 490 x 742 x 655 = 196231397600
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
742 : 1, 2, 7, 14, 53, 106, 371, 742
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,490,742,655, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
490:2x 5x 7x 7
742:2x 7x 53
655:5x 131
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 196231397600/(1x140)
LCM = 196231397600/140
LCM = 1401652840
Thus, we can understand that the LCM of 824,490,742,655 is 1401652840.
