Given numbers are 482,742,689,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 482,742,689,120 is 139481160.
Find LCM of 482,742,689,120 with Prime Factorization
2 | 482, 742, 689, 120 |
53 | 241, 371, 689, 60 |
241, 7, 13, 60 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 241 x 7 x 13 x 60 = 139481160
Therefore, the lowest common multiple of 482,742,689,120 is 139481160.
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.
482 x 742 x 689 x 120 = 29570005920
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.
482 : 1, 2, 241, 482
742 : 1, 2, 7, 14, 53, 106, 371, 742
689 : 1, 13, 53, 689
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 482,742,689,120, is 1.
Now, the common factors can be found like this.
482:2x 241
742:2x 7x 53
689:13x 53
120:2x 2x 2x 3x 5
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 53 = 212
Therefore, the value for common factors is 212.
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 = 29570005920/(1x212)
LCM = 29570005920/212
LCM = 139481160
Thus, we can understand that the LCM of 482,742,689,120 is 139481160.
