Given numbers are 530,555,642,621,524
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,555,642,621,524 is 341392725540.
Find LCM of 530,555,642,621,524 with Prime Factorization
| 2 | 530, 555, 642, 621, 524 |
| 3 | 265, 555, 321, 621, 262 |
| 5 | 265, 185, 107, 207, 262 |
| 53, 37, 107, 207, 262 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 53 x 37 x 107 x 207 x 262 = 341392725540
Therefore, the lowest common multiple of 530,555,642,621,524 is 341392725540.
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.
530 x 555 x 642 x 621 x 524 = 61450690597200
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
555 : 1, 3, 5, 15, 37, 111, 185, 555
642 : 1, 2, 3, 6, 107, 214, 321, 642
621 : 1, 3, 9, 23, 27, 69, 207, 621
524 : 1, 2, 4, 131, 262, 524
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,555,642,621,524, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
555:3x 5x 37
642:2x 3x 107
621:3x 3x 3x 23
524:2x 2x 131
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 61450690597200/(1x180)
LCM = 61450690597200/180
LCM = 341392725540
Thus, we can understand that the LCM of 530,555,642,621,524 is 341392725540.
