Given numbers are 937,858,991,420,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 937,858,991,420,931 is 7417374624660.
Find LCM of 937,858,991,420,931 with Prime Factorization
| 2 | 937, 858, 991, 420, 931 |
| 3 | 937, 429, 991, 210, 931 |
| 7 | 937, 143, 991, 70, 931 |
| 937, 143, 991, 10, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 937 x 143 x 991 x 10 x 133 = 7417374624660
Therefore, the lowest common multiple of 937,858,991,420,931 is 7417374624660.
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.
937 x 858 x 991 x 420 x 931 = 311529734235720
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.
937 : 1, 937
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
991 : 1, 991
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 937,858,991,420,931, is 1.
Now, the common factors can be found like this.
937:937
858:2x 3x 11x 13
991:991
420:2x 2x 3x 5x 7
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 311529734235720/(1x42)
LCM = 311529734235720/42
LCM = 7417374624660
Thus, we can understand that the LCM of 937,858,991,420,931 is 7417374624660.
