Given numbers are 534,476,720,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 534,476,720,856 is 815930640.
Find LCM of 534,476,720,856 with Prime Factorization
| 2 | 534, 476, 720, 856 |
| 2 | 267, 238, 360, 428 |
| 2 | 267, 119, 180, 214 |
| 3 | 267, 119, 90, 107 |
| 89, 119, 30, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 89 x 119 x 30 x 107 = 815930640
Therefore, the lowest common multiple of 534,476,720,856 is 815930640.
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.
534 x 476 x 720 x 856 = 156658682880
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.
534 : 1, 2, 3, 6, 89, 178, 267, 534
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
856 : 1, 2, 4, 8, 107, 214, 428, 856
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 534,476,720,856, is 2.
Now, the common factors can be found like this.
534:2x 3x 89
476:2x 2x 7x 17
720:2x 2x 2x 2x 3x 3x 5
856:2x 2x 2x 107
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 = 156658682880/(2x96)
LCM = 156658682880/192
LCM = 815930640
Thus, we can understand that the LCM of 534,476,720,856 is 815930640.
