The LCM of 578,915,561,340 is 11635140.
Find LCM of 578,915,561,340 with Prime Factorization
| 2 | 578, 915, 561, 340 |
| 3 | 289, 915, 561, 170 |
| 5 | 289, 305, 187, 170 |
| 17 | 289, 61, 187, 34 |
| 17, 61, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 17 x 61 x 11 x 2 = 11635140
Therefore, the lowest common multiple of 578,915,561,340 is 11635140.
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.
578 x 915 x 561 x 340 = 100876663800
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.
578 : 1, 2, 17, 34, 289, 578
915 : 1, 3, 5, 15, 61, 183, 305, 915
561 : 1, 3, 11, 17, 33, 51, 187, 561
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 578,915,561,340, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
915:3x 5x 61
561:3x 11x 17
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.
2x 3x 5x 17x 17 = 8670
Therefore, the value for common factors is 8670.
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 = 100876663800/(1x8670)
LCM = 100876663800/8670
LCM = 11635140
Thus, we can understand that the LCM of 578,915,561,340 is 11635140.
