The LCM of 456,680,203,646 is 7868280.
Find LCM of 456,680,203,646 with Prime Factorization
| 2 | 456, 680, 203, 646 |
| 2 | 228, 340, 203, 323 |
| 2 | 114, 170, 203, 323 |
| 17 | 57, 85, 203, 323 |
| 19 | 57, 5, 203, 19 |
| 3, 5, 203, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 19 x 3 x 5 x 203 x 1 = 7868280
Therefore, the lowest common multiple of 456,680,203,646 is 7868280.
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.
456 x 680 x 203 x 646 = 40663271040
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
203 : 1, 7, 29, 203
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,680,203,646, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
680:2x 2x 2x 5x 17
203:7x 29
646:2x 17x 19
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 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 40663271040/(1x5168)
LCM = 40663271040/5168
LCM = 7868280
Thus, we can understand that the LCM of 456,680,203,646 is 7868280.
