Given numbers are 557,783,651,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,783,651,655 is 61989479685.
Find LCM of 557,783,651,655 with Prime Factorization
3 | 557, 783, 651, 655 |
557, 261, 217, 655 |
Multiply the prime numbers at the bottom and the left side.
3 x 557 x 261 x 217 x 655 = 61989479685
Therefore, the lowest common multiple of 557,783,651,655 is 61989479685.
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.
557 x 783 x 651 x 655 = 185968439055
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.
557 : 1, 557
783 : 1, 3, 9, 27, 29, 87, 261, 783
651 : 1, 3, 7, 21, 31, 93, 217, 651
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,783,651,655, is 1.
Now, the common factors can be found like this.
557:557
783:3x 3x 3x 29
651:3x 7x 31
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 185968439055/(1x3)
LCM = 185968439055/3
LCM = 61989479685
Thus, we can understand that the LCM of 557,783,651,655 is 61989479685.
