The LCM of 197,680,820,726,776 is 193391487960.
Find LCM of 197,680,820,726,776 with Prime Factorization
| 2 | 197, 680, 820, 726, 776 |
| 2 | 197, 340, 410, 363, 388 |
| 2 | 197, 170, 205, 363, 194 |
| 5 | 197, 85, 205, 363, 97 |
| 197, 17, 41, 363, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 197 x 17 x 41 x 363 x 97 = 193391487960
Therefore, the lowest common multiple of 197,680,820,726,776 is 193391487960.
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.
197 x 680 x 820 x 726 x 776 = 61885276147200
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.
197 : 1, 197
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,680,820,726,776, is 1.
Now, the common factors can be found like this.
197:197
680:2x 2x 2x 5x 17
820:2x 2x 5x 41
726:2x 3x 11x 11
776:2x 2x 2x 97
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 = 61885276147200/(1x320)
LCM = 61885276147200/320
LCM = 193391487960
Thus, we can understand that the LCM of 197,680,820,726,776 is 193391487960.
