Given numbers are 782,748,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,748,557 is 9582628.
Find LCM of 782,748,557 with Prime Factorization
| 2 | 782, 748, 557 |
| 17 | 391, 374, 557 |
| 23, 22, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 22 x 557 = 9582628
Therefore, the lowest common multiple of 782,748,557 is 9582628.
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 748 x 557 = 325809352
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,748,557, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
748:2x 2x 11x 17
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 325809352/(1x34)
LCM = 325809352/34
LCM = 9582628
Thus, we can understand that the LCM of 782,748,557 is 9582628.
