The LCM of 376,605,774,556,390 is 159078811320.
Find LCM of 376,605,774,556,390 with Prime Factorization
| 2 | 376, 605, 774, 556, 390 |
| 2 | 188, 605, 387, 278, 195 |
| 3 | 94, 605, 387, 139, 195 |
| 5 | 94, 605, 129, 139, 65 |
| 94, 121, 129, 139, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 94 x 121 x 129 x 139 x 13 = 159078811320
Therefore, the lowest common multiple of 376,605,774,556,390 is 159078811320.
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.
376 x 605 x 774 x 556 x 390 = 38178914716800
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.
376 : 1, 2, 4, 8, 47, 94, 188, 376
605 : 1, 5, 11, 55, 121, 605
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
556 : 1, 2, 4, 139, 278, 556
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 376,605,774,556,390, is 1.
Now, the common factors can be found like this.
376:2x 2x 2x 47
605:5x 11x 11
774:2x 3x 3x 43
556:2x 2x 139
390:2x 3x 5x 13
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 38178914716800/(1x240)
LCM = 38178914716800/240
LCM = 159078811320
Thus, we can understand that the LCM of 376,605,774,556,390 is 159078811320.
