Find LCM of 989,143,120,512,197 with Prime Factorization
2 | 989, 143, 120, 512, 197 |
2 | 989, 143, 60, 256, 197 |
2 | 989, 143, 30, 128, 197 |
989, 143, 15, 64, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 989 x 143 x 15 x 64 x 197 = 213973393920
Therefore, the lowest common multiple of 989,143,120,512,197 is 213973393920.
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.
989 x 143 x 120 x 512 x 197 = 1711787151360
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.
989 : 1, 23, 43, 989
143 : 1, 11, 13, 143
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,143,120,512,197, is 1.
Now, the common factors can be found like this.
989:23x 43
143:11x 13
120:2x 2x 2x 3x 5
512:2x 2x 2x 2x 2x 2x 2x 2x 2
197:197
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 2 = 8
Therefore, the value for common factors is 8.
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 = 1711787151360/(1x8)
LCM = 1711787151360/8
LCM = 213973393920
Thus, we can understand that the LCM of 989,143,120,512,197 is 213973393920.
