Find LCM of 130,987,991,846,247 with Prime Factorization
| 2 | 130, 987, 991, 846, 247 |
| 3 | 65, 987, 991, 423, 247 |
| 13 | 65, 329, 991, 141, 247 |
| 47 | 5, 329, 991, 141, 19 |
| 5, 7, 991, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 47 x 5 x 7 x 991 x 3 x 19 = 7247846970
Therefore, the lowest common multiple of 130,987,991,846,247 is 7247846970.
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.
130 x 987 x 991 x 846 x 247 = 26570606992020
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
987 : 1, 3, 7, 21, 47, 141, 329, 987
991 : 1, 991
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,987,991,846,247, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
987:3x 7x 47
991:991
846:2x 3x 3x 47
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13x 47 = 3666
Therefore, the value for common factors is 3666.
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 = 26570606992020/(1x3666)
LCM = 26570606992020/3666
LCM = 7247846970
Thus, we can understand that the LCM of 130,987,991,846,247 is 7247846970.
