Given numbers are 542,629,245,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,629,245,931 is 1586973290.
Find LCM of 542,629,245,931 with Prime Factorization
| 7 | 542, 629, 245, 931 |
| 7 | 542, 629, 35, 133 |
| 542, 629, 5, 19 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 542 x 629 x 5 x 19 = 1586973290
Therefore, the lowest common multiple of 542,629,245,931 is 1586973290.
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.
542 x 629 x 245 x 931 = 77761691210
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.
542 : 1, 2, 271, 542
629 : 1, 17, 37, 629
245 : 1, 5, 7, 35, 49, 245
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,629,245,931, is 1.
Now, the common factors can be found like this.
542:2x 271
629:17x 37
245:5x 7x 7
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 77761691210/(1x49)
LCM = 77761691210/49
LCM = 1586973290
Thus, we can understand that the LCM of 542,629,245,931 is 1586973290.
