Given numbers are 782,722,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,722,427 is 120542954.
Find LCM of 782,722,427 with Prime Factorization
| 2 | 782, 722, 427 |
| 391, 361, 427 |
Multiply the prime numbers at the bottom and the left side.
2 x 391 x 361 x 427 = 120542954
Therefore, the lowest common multiple of 782,722,427 is 120542954.
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 722 x 427 = 241085908
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
722 : 1, 2, 19, 38, 361, 722
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,722,427, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
722:2x 19x 19
427:7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 241085908/(1x2)
LCM = 241085908/2
LCM = 120542954
Thus, we can understand that the LCM of 782,722,427 is 120542954.
