Given numbers are 394,770,968,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,770,968,672 is 80092320.
Find LCM of 394,770,968,672 with Prime Factorization
| 2 | 394, 770, 968, 672 |
| 2 | 197, 385, 484, 336 |
| 2 | 197, 385, 242, 168 |
| 7 | 197, 385, 121, 84 |
| 11 | 197, 55, 121, 12 |
| 197, 5, 11, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 197 x 5 x 11 x 12 = 80092320
Therefore, the lowest common multiple of 394,770,968,672 is 80092320.
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.
394 x 770 x 968 x 672 = 197347476480
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.
394 : 1, 2, 197, 394
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,770,968,672, is 2.
Now, the common factors can be found like this.
394:2x 197
770:2x 5x 7x 11
968:2x 2x 2x 11x 11
672:2x 2x 2x 2x 2x 3x 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 2x 7x 11 = 1232
Therefore, the value for common factors is 1232.
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 = 197347476480/(2x1232)
LCM = 197347476480/2464
LCM = 80092320
Thus, we can understand that the LCM of 394,770,968,672 is 80092320.
