Find LCM of 378,189,927,990,613 with Prime Factorization
| 2 | 378, 189, 927, 990, 613 |
| 3 | 189, 189, 927, 495, 613 |
| 3 | 63, 63, 309, 165, 613 |
| 3 | 21, 21, 103, 55, 613 |
| 7 | 7, 7, 103, 55, 613 |
| 1, 1, 103, 55, 613 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 1 x 1 x 103 x 55 x 613 = 1312659810
Therefore, the lowest common multiple of 378,189,927,990,613 is 1312659810.
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.
378 x 189 x 927 x 990 x 613 = 40191018062580
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
189 : 1, 3, 7, 9, 21, 27, 63, 189
927 : 1, 3, 9, 103, 309, 927
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
613 : 1, 613
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,189,927,990,613, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
189:3x 3x 3x 7
927:3x 3x 103
990:2x 3x 3x 5x 11
613:613
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 3x 3x 3x 3x 3x 3x 7 = 30618
Therefore, the value for common factors is 30618.
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 = 40191018062580/(1x30618)
LCM = 40191018062580/30618
LCM = 1312659810
Thus, we can understand that the LCM of 378,189,927,990,613 is 1312659810.
