Given numbers are 518,600,757,740,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,600,757,740,642 is 12587244600.
Find LCM of 518,600,757,740,642 with Prime Factorization
| 2 | 518, 600, 757, 740, 642 |
| 2 | 259, 300, 757, 370, 321 |
| 3 | 259, 150, 757, 185, 321 |
| 5 | 259, 50, 757, 185, 107 |
| 37 | 259, 10, 757, 37, 107 |
| 7, 10, 757, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 37 x 7 x 10 x 757 x 1 x 107 = 12587244600
Therefore, the lowest common multiple of 518,600,757,740,642 is 12587244600.
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.
518 x 600 x 757 x 740 x 642 = 111774732048000
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
757 : 1, 757
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,600,757,740,642, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
600:2x 2x 2x 3x 5x 5
757:757
740:2x 2x 5x 37
642:2x 3x 107
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 2x 2x 3x 5x 37 = 8880
Therefore, the value for common factors is 8880.
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 = 111774732048000/(1x8880)
LCM = 111774732048000/8880
LCM = 12587244600
Thus, we can understand that the LCM of 518,600,757,740,642 is 12587244600.
