Find LCM of 942,970,561,970,847 with Prime Factorization
| 2 | 942, 970, 561, 970, 847 |
| 3 | 471, 485, 561, 485, 847 |
| 5 | 157, 485, 187, 485, 847 |
| 11 | 157, 97, 187, 97, 847 |
| 97 | 157, 97, 17, 97, 77 |
| 157, 1, 17, 1, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 97 x 157 x 1 x 17 x 1 x 77 = 6578471130
Therefore, the lowest common multiple of 942,970,561,970,847 is 6578471130.
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.
942 x 970 x 561 x 970 x 847 = 421153721742600
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
970 : 1, 2, 5, 10, 97, 194, 485, 970
561 : 1, 3, 11, 17, 33, 51, 187, 561
970 : 1, 2, 5, 10, 97, 194, 485, 970
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,970,561,970,847, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
970:2x 5x 97
561:3x 11x 17
970:2x 5x 97
847:7x 11x 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 3x 5x 11x 97 = 64020
Therefore, the value for common factors is 64020.
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 = 421153721742600/(1x64020)
LCM = 421153721742600/64020
LCM = 6578471130
Thus, we can understand that the LCM of 942,970,561,970,847 is 6578471130.
