Find LCM of 920,200,785,799,438 with Prime Factorization
2 | 920, 200, 785, 799, 438 |
2 | 460, 100, 785, 799, 219 |
2 | 230, 50, 785, 799, 219 |
5 | 115, 25, 785, 799, 219 |
23, 5, 157, 799, 219 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 5 x 157 x 799 x 219 = 126371278200
Therefore, the lowest common multiple of 920,200,785,799,438 is 126371278200.
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.
920 x 200 x 785 x 799 x 438 = 50548511280000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
785 : 1, 5, 157, 785
799 : 1, 17, 47, 799
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,200,785,799,438, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
200:2x 2x 2x 5x 5
785:5x 157
799:17x 47
438:2x 3x 73
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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 50548511280000/(1x400)
LCM = 50548511280000/400
LCM = 126371278200
Thus, we can understand that the LCM of 920,200,785,799,438 is 126371278200.
