Find LCM of 674,221,992,248,979 with Prime Factorization
| 2 | 674, 221, 992, 248, 979 |
| 2 | 337, 221, 496, 124, 979 |
| 2 | 337, 221, 248, 62, 979 |
| 31 | 337, 221, 124, 31, 979 |
| 337, 221, 4, 1, 979 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 337 x 221 x 4 x 1 x 979 = 72329679136
Therefore, the lowest common multiple of 674,221,992,248,979 is 72329679136.
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.
674 x 221 x 992 x 248 x 979 = 35875520851456
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.
674 : 1, 2, 337, 674
221 : 1, 13, 17, 221
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
248 : 1, 2, 4, 8, 31, 62, 124, 248
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,221,992,248,979, is 1.
Now, the common factors can be found like this.
674:2x 337
221:13x 17
992:2x 2x 2x 2x 2x 31
248:2x 2x 2x 31
979:11x 89
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 31 = 496
Therefore, the value for common factors is 496.
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 = 35875520851456/(1x496)
LCM = 35875520851456/496
LCM = 72329679136
Thus, we can understand that the LCM of 674,221,992,248,979 is 72329679136.
