Find LCM of 897,391,456,900,128 with Prime Factorization
2 | 897, 391, 456, 900, 128 |
2 | 897, 391, 228, 450, 64 |
2 | 897, 391, 114, 225, 32 |
3 | 897, 391, 57, 225, 16 |
23 | 299, 391, 19, 75, 16 |
13, 17, 19, 75, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 13 x 17 x 19 x 75 x 16 = 2781417600
Therefore, the lowest common multiple of 897,391,456,900,128 is 2781417600.
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.
897 x 391 x 456 x 900 x 128 = 18424110182400
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
391 : 1, 17, 23, 391
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,391,456,900,128, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
391:17x 23
456:2x 2x 2x 3x 19
900:2x 2x 3x 3x 5x 5
128:2x 2x 2x 2x 2x 2x 2
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 2x 3x 3x 23 = 6624
Therefore, the value for common factors is 6624.
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 = 18424110182400/(1x6624)
LCM = 18424110182400/6624
LCM = 2781417600
Thus, we can understand that the LCM of 897,391,456,900,128 is 2781417600.
