Find LCM of 128,187,557,450,700 with Prime Factorization
2 | 128, 187, 557, 450, 700 |
2 | 64, 187, 557, 225, 350 |
5 | 32, 187, 557, 225, 175 |
5 | 32, 187, 557, 45, 35 |
32, 187, 557, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 32 x 187 x 557 x 9 x 7 = 20998454400
Therefore, the lowest common multiple of 128,187,557,450,700 is 20998454400.
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.
128 x 187 x 557 x 450 x 700 = 4199690880000
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
187 : 1, 11, 17, 187
557 : 1, 557
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,187,557,450,700, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
187:11x 17
557:557
450:2x 3x 3x 5x 5
700:2x 2x 5x 5x 7
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 4199690880000/(1x200)
LCM = 4199690880000/200
LCM = 20998454400
Thus, we can understand that the LCM of 128,187,557,450,700 is 20998454400.
