Given numbers are 562,680,689,281
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 562,680,689,281 is 131654120.
Find LCM of 562,680,689,281 with Prime Factorization
| 2 | 562, 680, 689, 281 |
| 281 | 281, 340, 689, 281 |
| 1, 340, 689, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 281 x 1 x 340 x 689 x 1 = 131654120
Therefore, the lowest common multiple of 562,680,689,281 is 131654120.
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.
562 x 680 x 689 x 281 = 73989615440
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.
562 : 1, 2, 281, 562
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
689 : 1, 13, 53, 689
281 : 1, 281
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 562,680,689,281, is 1.
Now, the common factors can be found like this.
562:2x 281
680:2x 2x 2x 5x 17
689:13x 53
281:281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 281 = 562
Therefore, the value for common factors is 562.
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 = 73989615440/(1x562)
LCM = 73989615440/562
LCM = 131654120
Thus, we can understand that the LCM of 562,680,689,281 is 131654120.
