Given numbers are 308,300,818,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,300,818,392 is 132270600.
Find LCM of 308,300,818,392 with Prime Factorization
2 | 308, 300, 818, 392 |
2 | 154, 150, 409, 196 |
7 | 77, 75, 409, 98 |
11, 75, 409, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 75 x 409 x 14 = 132270600
Therefore, the lowest common multiple of 308,300,818,392 is 132270600.
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.
308 x 300 x 818 x 392 = 29628614400
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
818 : 1, 2, 409, 818
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,300,818,392, is 2.
Now, the common factors can be found like this.
308:2x 2x 7x 11
300:2x 2x 3x 5x 5
818:2x 409
392:2x 2x 2x 7x 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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 29628614400/(2x112)
LCM = 29628614400/224
LCM = 132270600
Thus, we can understand that the LCM of 308,300,818,392 is 132270600.
