Given numbers are 863,740,357,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,740,357,392 is 3191822760.
Find LCM of 863,740,357,392 with Prime Factorization
| 2 | 863, 740, 357, 392 |
| 2 | 863, 370, 357, 196 |
| 7 | 863, 185, 357, 98 |
| 863, 185, 51, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 863 x 185 x 51 x 14 = 3191822760
Therefore, the lowest common multiple of 863,740,357,392 is 3191822760.
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.
863 x 740 x 357 x 392 = 89371037280
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.
863 : 1, 863
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
357 : 1, 3, 7, 17, 21, 51, 119, 357
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,740,357,392, is 1.
Now, the common factors can be found like this.
863:863
740:2x 2x 5x 37
357:3x 7x 17
392:2x 2x 2x 7x 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 7 = 28
Therefore, the value for common factors is 28.
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 = 89371037280/(1x28)
LCM = 89371037280/28
LCM = 3191822760
Thus, we can understand that the LCM of 863,740,357,392 is 3191822760.
