Find LCM of 378,253,918,168 with Prime Factorization
2 | 378, 253, 918, 168 |
3 | 189, 253, 459, 84 |
3 | 63, 253, 153, 28 |
3 | 21, 253, 51, 28 |
7 | 7, 253, 17, 28 |
1, 253, 17, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 1 x 253 x 17 x 4 = 6503112
Therefore, the lowest common multiple of 378,253,918,168 is 6503112.
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.
378 x 253 x 918 x 168 = 14749058016
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
253 : 1, 11, 23, 253
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,253,918,168, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
253:11x 23
918:2x 3x 3x 3x 17
168:2x 2x 2x 3x 7
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 3x 7 = 2268
Therefore, the value for common factors is 2268.
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 = 14749058016/(1x2268)
LCM = 14749058016/2268
LCM = 6503112
Thus, we can understand that the LCM of 378,253,918,168 is 6503112.
