Find LCM of 645,157,903,436,200 with Prime Factorization
| 2 | 645, 157, 903, 436, 200 |
| 2 | 645, 157, 903, 218, 100 |
| 3 | 645, 157, 903, 109, 50 |
| 5 | 215, 157, 301, 109, 50 |
| 43 | 43, 157, 301, 109, 10 |
| 1, 157, 7, 109, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 1 x 157 x 7 x 109 x 10 = 3090607800
Therefore, the lowest common multiple of 645,157,903,436,200 is 3090607800.
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.
645 x 157 x 903 x 436 x 200 = 7973768124000
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
157 : 1, 157
903 : 1, 3, 7, 21, 43, 129, 301, 903
436 : 1, 2, 4, 109, 218, 436
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,157,903,436,200, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
157:157
903:3x 7x 43
436:2x 2x 109
200:2x 2x 2x 5x 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 43 = 2580
Therefore, the value for common factors is 2580.
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 = 7973768124000/(1x2580)
LCM = 7973768124000/2580
LCM = 3090607800
Thus, we can understand that the LCM of 645,157,903,436,200 is 3090607800.
