The LCM of 657,986,986,783 is 1943406.
Find LCM of 657,986,986,783 with Prime Factorization
2 | 657, 986, 986, 783 |
3 | 657, 493, 493, 783 |
3 | 219, 493, 493, 261 |
17 | 73, 493, 493, 87 |
29 | 73, 29, 29, 87 |
73, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 29 x 73 x 1 x 1 x 3 = 1943406
Therefore, the lowest common multiple of 657,986,986,783 is 1943406.
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.
657 x 986 x 986 x 783 = 500127760476
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.
657 : 1, 3, 9, 73, 219, 657
986 : 1, 2, 17, 29, 34, 58, 493, 986
986 : 1, 2, 17, 29, 34, 58, 493, 986
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,986,986,783, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
986:2x 17x 29
986:2x 17x 29
783:3x 3x 3x 29
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 17x 29x 29 = 257346
Therefore, the value for common factors is 257346.
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 = 500127760476/(1x257346)
LCM = 500127760476/257346
LCM = 1943406
Thus, we can understand that the LCM of 657,986,986,783 is 1943406.
