Given numbers are 782,782,402,734
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,782,402,734 is 57685794.
Find LCM of 782,782,402,734 with Prime Factorization
| 2 | 782, 782, 402, 734 |
| 17 | 391, 391, 201, 367 |
| 23 | 23, 23, 201, 367 |
| 1, 1, 201, 367 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 1 x 1 x 201 x 367 = 57685794
Therefore, the lowest common multiple of 782,782,402,734 is 57685794.
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.
782 x 782 x 402 x 734 = 180441163632
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
782 : 1, 2, 17, 23, 34, 46, 391, 782
402 : 1, 2, 3, 6, 67, 134, 201, 402
734 : 1, 2, 367, 734
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,782,402,734, is 2.
Now, the common factors can be found like this.
782:2x 17x 23
782:2x 17x 23
402:2x 3x 67
734:2x 367
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 = 180441163632/(2x1564)
LCM = 180441163632/3128
LCM = 57685794
Thus, we can understand that the LCM of 782,782,402,734 is 57685794.
