Given numbers are 986,786,435,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,786,435,651 is 420435330.
Find LCM of 986,786,435,651 with Prime Factorization
| 2 | 986, 786, 435, 651 |
| 3 | 493, 393, 435, 651 |
| 29 | 493, 131, 145, 217 |
| 17, 131, 5, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 17 x 131 x 5 x 217 = 420435330
Therefore, the lowest common multiple of 986,786,435,651 is 420435330.
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 786 x 435 x 651 = 219467242260
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
435 : 1, 3, 5, 15, 29, 87, 145, 435
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,786,435,651, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
786:2x 3x 131
435:3x 5x 29
651:3x 7x 31
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 3x 29 = 522
Therefore, the value for common factors is 522.
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 = 219467242260/(1x522)
LCM = 219467242260/522
LCM = 420435330
Thus, we can understand that the LCM of 986,786,435,651 is 420435330.
