Find LCM of 240,513,678,912,556 with Prime Factorization
| 2 | 240, 513, 678, 912, 556 |
| 2 | 120, 513, 339, 456, 278 |
| 2 | 60, 513, 339, 228, 139 |
| 2 | 30, 513, 339, 114, 139 |
| 3 | 15, 513, 339, 57, 139 |
| 19 | 5, 171, 113, 19, 139 |
| 5, 9, 113, 1, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 19 x 5 x 9 x 113 x 1 x 139 = 644615280
Therefore, the lowest common multiple of 240,513,678,912,556 is 644615280.
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.
240 x 513 x 678 x 912 x 556 = 42328017745920
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
513 : 1, 3, 9, 19, 27, 57, 171, 513
678 : 1, 2, 3, 6, 113, 226, 339, 678
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,513,678,912,556, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
513:3x 3x 3x 19
678:2x 3x 113
912:2x 2x 2x 2x 3x 19
556:2x 2x 139
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 2x 2x 2x 3x 3x 3x 19 = 65664
Therefore, the value for common factors is 65664.
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 = 42328017745920/(1x65664)
LCM = 42328017745920/65664
LCM = 644615280
Thus, we can understand that the LCM of 240,513,678,912,556 is 644615280.
