Find LCM of 714,989,238,783 with Prime Factorization
| 2 | 714, 989, 238, 783 |
| 3 | 357, 989, 119, 783 |
| 7 | 119, 989, 119, 261 |
| 17 | 17, 989, 17, 261 |
| 1, 989, 1, 261 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 1 x 989 x 1 x 261 = 184304106
Therefore, the lowest common multiple of 714,989,238,783 is 184304106.
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.
714 x 989 x 238 x 783 = 131593131684
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
989 : 1, 23, 43, 989
238 : 1, 2, 7, 14, 17, 34, 119, 238
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,989,238,783, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
989:23x 43
238:2x 7x 17
783:3x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 17 = 714
Therefore, the value for common factors is 714.
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 = 131593131684/(1x714)
LCM = 131593131684/714
LCM = 184304106
Thus, we can understand that the LCM of 714,989,238,783 is 184304106.
