Given numbers are 781,309,146,304
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,309,146,304 is 5355573168.
Find LCM of 781,309,146,304 with Prime Factorization
2 | 781, 309, 146, 304 |
781, 309, 73, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 781 x 309 x 73 x 152 = 5355573168
Therefore, the lowest common multiple of 781,309,146,304 is 5355573168.
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.
781 x 309 x 146 x 304 = 10711146336
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.
781 : 1, 11, 71, 781
309 : 1, 3, 103, 309
146 : 1, 2, 73, 146
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,309,146,304, is 1.
Now, the common factors can be found like this.
781:11x 71
309:3x 103
146:2x 73
304:2x 2x 2x 2x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 10711146336/(1x2)
LCM = 10711146336/2
LCM = 5355573168
Thus, we can understand that the LCM of 781,309,146,304 is 5355573168.
