Find LCM of 428,723,241,924,220 with Prime Factorization
| 2 | 428, 723, 241, 924, 220 |
| 2 | 214, 723, 241, 462, 110 |
| 3 | 107, 723, 241, 231, 55 |
| 11 | 107, 241, 241, 77, 55 |
| 241 | 107, 241, 241, 7, 5 |
| 107, 1, 1, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 241 x 107 x 1 x 1 x 7 x 5 = 119135940
Therefore, the lowest common multiple of 428,723,241,924,220 is 119135940.
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.
428 x 723 x 241 x 924 x 220 = 15159810093120
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.
428 : 1, 2, 4, 107, 214, 428
723 : 1, 3, 241, 723
241 : 1, 241
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,723,241,924,220, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
723:3x 241
241:241
924:2x 2x 3x 7x 11
220:2x 2x 5x 11
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 3x 11x 241 = 127248
Therefore, the value for common factors is 127248.
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 = 15159810093120/(1x127248)
LCM = 15159810093120/127248
LCM = 119135940
Thus, we can understand that the LCM of 428,723,241,924,220 is 119135940.
