Given numbers are 979,147,946,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,147,946,860 is 123765180.
Find LCM of 979,147,946,860 with Prime Factorization
| 2 | 979, 147, 946, 860 |
| 11 | 979, 147, 473, 430 |
| 43 | 89, 147, 43, 430 |
| 89, 147, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 89 x 147 x 1 x 10 = 123765180
Therefore, the lowest common multiple of 979,147,946,860 is 123765180.
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.
979 x 147 x 946 x 860 = 117081860280
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.
979 : 1, 11, 89, 979
147 : 1, 3, 7, 21, 49, 147
946 : 1, 2, 11, 22, 43, 86, 473, 946
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,147,946,860, is 1.
Now, the common factors can be found like this.
979:11x 89
147:3x 7x 7
946:2x 11x 43
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 43 = 946
Therefore, the value for common factors is 946.
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 = 117081860280/(1x946)
LCM = 117081860280/946
LCM = 123765180
Thus, we can understand that the LCM of 979,147,946,860 is 123765180.
