Given numbers are 947,930,942,990,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,930,942,990,791 is 3609300181410.
Find LCM of 947,930,942,990,791 with Prime Factorization
2 | 947, 930, 942, 990, 791 |
3 | 947, 465, 471, 495, 791 |
5 | 947, 155, 157, 165, 791 |
947, 31, 157, 33, 791 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 947 x 31 x 157 x 33 x 791 = 3609300181410
Therefore, the lowest common multiple of 947,930,942,990,791 is 3609300181410.
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 930 x 942 x 990 x 791 = 649674032653800
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
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
942 : 1, 2, 3, 6, 157, 314, 471, 942
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,930,942,990,791, is 1.
Now, the common factors can be found like this.
947:947
930:2x 3x 5x 31
942:2x 3x 157
990:2x 3x 3x 5x 11
791:7x 113
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 649674032653800/(1x180)
LCM = 649674032653800/180
LCM = 3609300181410
Thus, we can understand that the LCM of 947,930,942,990,791 is 3609300181410.
