Find LCM of 770,308,143,979,203 with Prime Factorization
| 2 | 770, 308, 143, 979, 203 |
| 7 | 385, 154, 143, 979, 203 |
| 11 | 55, 22, 143, 979, 29 |
| 5, 2, 13, 89, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 5 x 2 x 13 x 89 x 29 = 51671620
Therefore, the lowest common multiple of 770,308,143,979,203 is 51671620.
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.
770 x 308 x 143 x 979 x 203 = 6739942769560
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
143 : 1, 11, 13, 143
979 : 1, 11, 89, 979
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,308,143,979,203, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
308:2x 2x 7x 11
143:11x 13
979:11x 89
203:7x 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 7x 7x 11x 11x 11 = 130438
Therefore, the value for common factors is 130438.
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 = 6739942769560/(1x130438)
LCM = 6739942769560/130438
LCM = 51671620
Thus, we can understand that the LCM of 770,308,143,979,203 is 51671620.
