Given numbers are 556,806,139,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,806,139,902 is 101054668.
Find LCM of 556,806,139,902 with Prime Factorization
| 2 | 556, 806, 139, 902 |
| 139 | 278, 403, 139, 451 |
| 2, 403, 1, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 2 x 403 x 1 x 451 = 101054668
Therefore, the lowest common multiple of 556,806,139,902 is 101054668.
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.
556 x 806 x 139 x 902 = 56186395408
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.
556 : 1, 2, 4, 139, 278, 556
806 : 1, 2, 13, 26, 31, 62, 403, 806
139 : 1, 139
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,806,139,902, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
806:2x 13x 31
139:139
902:2x 11x 41
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 139 = 556
Therefore, the value for common factors is 556.
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 = 56186395408/(1x556)
LCM = 56186395408/556
LCM = 101054668
Thus, we can understand that the LCM of 556,806,139,902 is 101054668.
