The LCM of 794,620,189,921,896 is 457016999040.
Find LCM of 794,620,189,921,896 with Prime Factorization
| 2 | 794, 620, 189, 921, 896 |
| 2 | 397, 310, 189, 921, 448 |
| 3 | 397, 155, 189, 921, 224 |
| 7 | 397, 155, 63, 307, 224 |
| 397, 155, 9, 307, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 397 x 155 x 9 x 307 x 32 = 457016999040
Therefore, the lowest common multiple of 794,620,189,921,896 is 457016999040.
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.
794 x 620 x 189 x 921 x 896 = 76778855838720
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.
794 : 1, 2, 397, 794
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
189 : 1, 3, 7, 9, 21, 27, 63, 189
921 : 1, 3, 307, 921
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,620,189,921,896, is 1.
Now, the common factors can be found like this.
794:2x 397
620:2x 2x 5x 31
189:3x 3x 3x 7
921:3x 307
896:2x 2x 2x 2x 2x 2x 2x 7
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 76778855838720/(1x168)
LCM = 76778855838720/168
LCM = 457016999040
Thus, we can understand that the LCM of 794,620,189,921,896 is 457016999040.
