Find LCM of 247,342,249,874,648 with Prime Factorization
2 | 247, 342, 249, 874, 648 |
3 | 247, 171, 249, 437, 324 |
3 | 247, 57, 83, 437, 108 |
19 | 247, 19, 83, 437, 36 |
13, 1, 83, 23, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 13 x 1 x 83 x 23 x 36 = 305546904
Therefore, the lowest common multiple of 247,342,249,874,648 is 305546904.
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.
247 x 342 x 249 x 874 x 648 = 11912662693152
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.
247 : 1, 13, 19, 247
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
249 : 1, 3, 83, 249
874 : 1, 2, 19, 23, 38, 46, 437, 874
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,342,249,874,648, is 1.
Now, the common factors can be found like this.
247:13x 19
342:2x 3x 3x 19
249:3x 83
874:2x 19x 23
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3x 19x 19 = 38988
Therefore, the value for common factors is 38988.
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 = 11912662693152/(1x38988)
LCM = 11912662693152/38988
LCM = 305546904
Thus, we can understand that the LCM of 247,342,249,874,648 is 305546904.
