Find LCM of 357,343,579,989,340 with Prime Factorization
| 3 | 357, 343, 579, 989, 340 |
| 7 | 119, 343, 193, 989, 340 |
| 17 | 17, 49, 193, 989, 340 |
| 1, 49, 193, 989, 20 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 17 x 1 x 49 x 193 x 989 x 20 = 66780227220
Therefore, the lowest common multiple of 357,343,579,989,340 is 66780227220.
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.
357 x 343 x 579 x 989 x 340 = 23840541117540
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
343 : 1, 7, 49, 343
579 : 1, 3, 193, 579
989 : 1, 23, 43, 989
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,343,579,989,340, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
343:7x 7x 7
579:3x 193
989:23x 43
340:2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 17 = 357
Therefore, the value for common factors is 357.
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 = 23840541117540/(1x357)
LCM = 23840541117540/357
LCM = 66780227220
Thus, we can understand that the LCM of 357,343,579,989,340 is 66780227220.
