Given numbers are 689,538,534,848
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,538,534,848 is 791776752.
Find LCM of 689,538,534,848 with Prime Factorization
| 2 | 689, 538, 534, 848 |
| 53 | 689, 269, 267, 424 |
| 13, 269, 267, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 13 x 269 x 267 x 8 = 791776752
Therefore, the lowest common multiple of 689,538,534,848 is 791776752.
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.
689 x 538 x 534 x 848 = 167856671424
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.
689 : 1, 13, 53, 689
538 : 1, 2, 269, 538
534 : 1, 2, 3, 6, 89, 178, 267, 534
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,538,534,848, is 1.
Now, the common factors can be found like this.
689:13x 53
538:2x 269
534:2x 3x 89
848:2x 2x 2x 2x 53
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 53 = 212
Therefore, the value for common factors is 212.
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 = 167856671424/(1x212)
LCM = 167856671424/212
LCM = 791776752
Thus, we can understand that the LCM of 689,538,534,848 is 791776752.
