Given numbers are 546,478,657,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,478,657,360 is 571563720.
Find LCM of 546,478,657,360 with Prime Factorization
| 2 | 546, 478, 657, 360 |
| 3 | 273, 239, 657, 180 |
| 3 | 91, 239, 219, 60 |
| 91, 239, 73, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 91 x 239 x 73 x 20 = 571563720
Therefore, the lowest common multiple of 546,478,657,360 is 571563720.
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.
546 x 478 x 657 x 360 = 61728881760
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
478 : 1, 2, 239, 478
657 : 1, 3, 9, 73, 219, 657
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,478,657,360, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
478:2x 239
657:3x 3x 73
360:2x 2x 2x 3x 3x 5
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 61728881760/(1x108)
LCM = 61728881760/108
LCM = 571563720
Thus, we can understand that the LCM of 546,478,657,360 is 571563720.
