Given numbers are 465,642,535,110,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 465,642,535,110,640 is 70055040.
Find LCM of 465,642,535,110,640 with Prime Factorization
| 2 | 465, 642, 535, 110, 640 |
| 3 | 465, 321, 535, 55, 320 |
| 5 | 155, 107, 535, 55, 320 |
| 107 | 31, 107, 107, 11, 64 |
| 31, 1, 1, 11, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 31 x 1 x 1 x 11 x 64 = 70055040
Therefore, the lowest common multiple of 465,642,535,110,640 is 70055040.
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.
465 x 642 x 535 x 110 x 640 = 11243833920000
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
642 : 1, 2, 3, 6, 107, 214, 321, 642
535 : 1, 5, 107, 535
110 : 1, 2, 5, 10, 11, 22, 55, 110
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,642,535,110,640, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
642:2x 3x 107
535:5x 107
110:2x 5x 11
640:2x 2x 2x 2x 2x 2x 2x 5
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 5x 5x 5x 107 = 160500
Therefore, the value for common factors is 160500.
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 = 11243833920000/(1x160500)
LCM = 11243833920000/160500
LCM = 70055040
Thus, we can understand that the LCM of 465,642,535,110,640 is 70055040.
