Given numbers are 947,644,709,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,644,709,709 is 432396412.
Find LCM of 947,644,709,709 with Prime Factorization
709 | 947, 644, 709, 709 |
947, 644, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
709 x 947 x 644 x 1 x 1 = 432396412
Therefore, the lowest common multiple of 947,644,709,709 is 432396412.
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.
947 x 644 x 709 x 709 = 306569056108
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.
947 : 1, 947
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
709 : 1, 709
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,644,709,709, is 1.
Now, the common factors can be found like this.
947:947
644:2x 2x 7x 23
709:709
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
709 = 709
Therefore, the value for common factors is 709.
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 = 306569056108/(1x709)
LCM = 306569056108/709
LCM = 432396412
Thus, we can understand that the LCM of 947,644,709,709 is 432396412.
