Find LCM of 770,955,686,268,658 with Prime Factorization
| 2 | 770, 955, 686, 268, 658 |
| 5 | 385, 955, 343, 134, 329 |
| 7 | 77, 191, 343, 134, 329 |
| 11, 191, 49, 134, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 191 x 49 x 134 x 47 = 45386096140
Therefore, the lowest common multiple of 770,955,686,268,658 is 45386096140.
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 955 x 686 x 268 x 658 = 88956748434400
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
955 : 1, 5, 191, 955
686 : 1, 2, 7, 14, 49, 98, 343, 686
268 : 1, 2, 4, 67, 134, 268
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,955,686,268,658, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
955:5x 191
686:2x 7x 7x 7
268:2x 2x 67
658:2x 7x 47
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 5x 7x 7 = 1960
Therefore, the value for common factors is 1960.
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 = 88956748434400/(1x1960)
LCM = 88956748434400/1960
LCM = 45386096140
Thus, we can understand that the LCM of 770,955,686,268,658 is 45386096140.
