Find LCM of 176,197,420,202,455 with Prime Factorization
2 | 176, 197, 420, 202, 455 |
2 | 88, 197, 210, 101, 455 |
5 | 44, 197, 105, 101, 455 |
7 | 44, 197, 21, 101, 91 |
44, 197, 3, 101, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 44 x 197 x 3 x 101 x 13 = 4780055280
Therefore, the lowest common multiple of 176,197,420,202,455 is 4780055280.
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.
176 x 197 x 420 x 202 x 455 = 1338415478400
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.
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
197 : 1, 197
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
202 : 1, 2, 101, 202
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 176,197,420,202,455, is 1.
Now, the common factors can be found like this.
176:2x 2x 2x 2x 11
197:197
420:2x 2x 3x 5x 7
202:2x 101
455:5x 7x 13
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 7 = 280
Therefore, the value for common factors is 280.
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 = 1338415478400/(1x280)
LCM = 1338415478400/280
LCM = 4780055280
Thus, we can understand that the LCM of 176,197,420,202,455 is 4780055280.
