Given numbers are 907,861,947,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 907,861,947,947 is 739537869.
Find LCM of 907,861,947,947 with Prime Factorization
947 | 907, 861, 947, 947 |
907, 861, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
947 x 907 x 861 x 1 x 1 = 739537869
Therefore, the lowest common multiple of 907,861,947,947 is 739537869.
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.
907 x 861 x 947 x 947 = 700342361943
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.
907 : 1, 907
861 : 1, 3, 7, 21, 41, 123, 287, 861
947 : 1, 947
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,861,947,947, is 1.
Now, the common factors can be found like this.
907:907
861:3x 7x 41
947:947
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
947 = 947
Therefore, the value for common factors is 947.
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 = 700342361943/(1x947)
LCM = 700342361943/947
LCM = 739537869
Thus, we can understand that the LCM of 907,861,947,947 is 739537869.
