Given numbers are 499,420,782,830,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 499,420,782,830,178 is 605333476860.
Find LCM of 499,420,782,830,178 with Prime Factorization
| 2 | 499, 420, 782, 830, 178 |
| 5 | 499, 210, 391, 415, 89 |
| 499, 42, 391, 83, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 499 x 42 x 391 x 83 x 89 = 605333476860
Therefore, the lowest common multiple of 499,420,782,830,178 is 605333476860.
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.
499 x 420 x 782 x 830 x 178 = 24213339074400
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.
499 : 1, 499
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
782 : 1, 2, 17, 23, 34, 46, 391, 782
830 : 1, 2, 5, 10, 83, 166, 415, 830
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 499,420,782,830,178, is 1.
Now, the common factors can be found like this.
499:499
420:2x 2x 3x 5x 7
782:2x 17x 23
830:2x 5x 83
178:2x 89
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 5 = 40
Therefore, the value for common factors is 40.
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 = 24213339074400/(1x40)
LCM = 24213339074400/40
LCM = 605333476860
Thus, we can understand that the LCM of 499,420,782,830,178 is 605333476860.
