Given numbers are 208,680,785,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,680,785,616 is 213733520.
Find LCM of 208,680,785,616 with Prime Factorization
| 2 | 208, 680, 785, 616 |
| 2 | 104, 340, 785, 308 |
| 2 | 52, 170, 785, 154 |
| 5 | 26, 85, 785, 77 |
| 26, 17, 157, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 26 x 17 x 157 x 77 = 213733520
Therefore, the lowest common multiple of 208,680,785,616 is 213733520.
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.
208 x 680 x 785 x 616 = 68394726400
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
785 : 1, 5, 157, 785
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,680,785,616, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
680:2x 2x 2x 5x 17
785:5x 157
616:2x 2x 2x 7x 11
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 2x 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 68394726400/(1x320)
LCM = 68394726400/320
LCM = 213733520
Thus, we can understand that the LCM of 208,680,785,616 is 213733520.
