Given numbers are 314,790,690,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 314,790,690,400 is 342322800.
Find LCM of 314,790,690,400 with Prime Factorization
2 | 314, 790, 690, 400 |
5 | 157, 395, 345, 200 |
157, 79, 69, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 157 x 79 x 69 x 40 = 342322800
Therefore, the lowest common multiple of 314,790,690,400 is 342322800.
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.
314 x 790 x 690 x 400 = 68464560000
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.
314 : 1, 2, 157, 314
790 : 1, 2, 5, 10, 79, 158, 395, 790
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 314,790,690,400, is 2.
Now, the common factors can be found like this.
314:2x 157
790:2x 5x 79
690:2x 3x 5x 23
400:2x 2x 2x 2x 5x 5
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 68464560000/(2x100)
LCM = 68464560000/200
LCM = 342322800
Thus, we can understand that the LCM of 314,790,690,400 is 342322800.
