Find LCM of 521,130,702,965,531 with Prime Factorization
| 2 | 521, 130, 702, 965, 531 |
| 3 | 521, 65, 351, 965, 531 |
| 3 | 521, 65, 117, 965, 177 |
| 5 | 521, 65, 39, 965, 59 |
| 13 | 521, 13, 39, 193, 59 |
| 521, 1, 3, 193, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 521 x 1 x 3 x 193 x 59 = 20823520770
Therefore, the lowest common multiple of 521,130,702,965,531 is 20823520770.
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.
521 x 130 x 702 x 965 x 531 = 24363519300900
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.
521 : 1, 521
130 : 1, 2, 5, 10, 13, 26, 65, 130
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
965 : 1, 5, 193, 965
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,130,702,965,531, is 1.
Now, the common factors can be found like this.
521:521
130:2x 5x 13
702:2x 3x 3x 3x 13
965:5x 193
531:3x 3x 59
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 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
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 = 24363519300900/(1x1170)
LCM = 24363519300900/1170
LCM = 20823520770
Thus, we can understand that the LCM of 521,130,702,965,531 is 20823520770.
