Given numbers are 578,456,868,528
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,456,868,528 is 629136816.
Find LCM of 578,456,868,528 with Prime Factorization
| 2 | 578, 456, 868, 528 |
| 2 | 289, 228, 434, 264 |
| 2 | 289, 114, 217, 132 |
| 3 | 289, 57, 217, 66 |
| 289, 19, 217, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 289 x 19 x 217 x 22 = 629136816
Therefore, the lowest common multiple of 578,456,868,528 is 629136816.
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 456 x 868 x 528 = 120794268672
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
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,456,868,528, is 2.
Now, the common factors can be found like this.
578:2x 17x 17
456:2x 2x 2x 3x 19
868:2x 2x 7x 31
528:2x 2x 2x 2x 3x 11
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 3 = 96
Therefore, the value for common factors is 96.
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 = 120794268672/(2x96)
LCM = 120794268672/192
LCM = 629136816
Thus, we can understand that the LCM of 578,456,868,528 is 629136816.
