Given numbers are 302,678,646,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 302,678,646,247 is 429885222.
Find LCM of 302,678,646,247 with Prime Factorization
| 2 | 302, 678, 646, 247 |
| 19 | 151, 339, 323, 247 |
| 151, 339, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 151 x 339 x 17 x 13 = 429885222
Therefore, the lowest common multiple of 302,678,646,247 is 429885222.
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.
302 x 678 x 646 x 247 = 32671276872
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.
302 : 1, 2, 151, 302
678 : 1, 2, 3, 6, 113, 226, 339, 678
646 : 1, 2, 17, 19, 34, 38, 323, 646
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,678,646,247, is 1.
Now, the common factors can be found like this.
302:2x 151
678:2x 3x 113
646:2x 17x 19
247:13x 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 19 = 76
Therefore, the value for common factors is 76.
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 = 32671276872/(1x76)
LCM = 32671276872/76
LCM = 429885222
Thus, we can understand that the LCM of 302,678,646,247 is 429885222.
