Given numbers are 392,989,989,674,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,989,989,674,346 is 22602598088.
Find LCM of 392,989,989,674,346 with Prime Factorization
2 | 392, 989, 989, 674, 346 |
23 | 196, 989, 989, 337, 173 |
43 | 196, 43, 43, 337, 173 |
196, 1, 1, 337, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 43 x 196 x 1 x 1 x 337 x 173 = 22602598088
Therefore, the lowest common multiple of 392,989,989,674,346 is 22602598088.
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.
392 x 989 x 989 x 674 x 346 = 89415878036128
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
989 : 1, 23, 43, 989
989 : 1, 23, 43, 989
674 : 1, 2, 337, 674
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,989,989,674,346, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
989:23x 43
989:23x 43
674:2x 337
346:2x 173
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 23x 43 = 3956
Therefore, the value for common factors is 3956.
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 = 89415878036128/(1x3956)
LCM = 89415878036128/3956
LCM = 22602598088
Thus, we can understand that the LCM of 392,989,989,674,346 is 22602598088.
