Given numbers are 986,902,947,790,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,902,947,790,666 is 55391709040470.
Find LCM of 986,902,947,790,666 with Prime Factorization
| 2 | 986, 902, 947, 790, 666 |
| 493, 451, 947, 395, 333 |
Multiply the prime numbers at the bottom and the left side.
2 x 493 x 451 x 947 x 395 x 333 = 55391709040470
Therefore, the lowest common multiple of 986,902,947,790,666 is 55391709040470.
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.
986 x 902 x 947 x 790 x 666 = 443133672323760
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
902 : 1, 2, 11, 22, 41, 82, 451, 902
947 : 1, 947
790 : 1, 2, 5, 10, 79, 158, 395, 790
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,902,947,790,666, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
902:2x 11x 41
947:947
790:2x 5x 79
666:2x 3x 3x 37
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 2 = 8
Therefore, the value for common factors is 8.
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 = 443133672323760/(1x8)
LCM = 443133672323760/8
LCM = 55391709040470
Thus, we can understand that the LCM of 986,902,947,790,666 is 55391709040470.
