Given numbers are 457,524,782,639,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,524,782,639,782 is 59830840332.
Find LCM of 457,524,782,639,782 with Prime Factorization
| 2 | 457, 524, 782, 639, 782 |
| 17 | 457, 262, 391, 639, 391 |
| 23 | 457, 262, 23, 639, 23 |
| 457, 262, 1, 639, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 457 x 262 x 1 x 639 x 1 = 59830840332
Therefore, the lowest common multiple of 457,524,782,639,782 is 59830840332.
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.
457 x 524 x 782 x 639 x 782 = 93575434279248
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.
457 : 1, 457
524 : 1, 2, 4, 131, 262, 524
782 : 1, 2, 17, 23, 34, 46, 391, 782
639 : 1, 3, 9, 71, 213, 639
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,524,782,639,782, is 1.
Now, the common factors can be found like this.
457:457
524:2x 2x 131
782:2x 17x 23
639:3x 3x 71
782:2x 17x 23
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 93575434279248/(1x1564)
LCM = 93575434279248/1564
LCM = 59830840332
Thus, we can understand that the LCM of 457,524,782,639,782 is 59830840332.
