Given numbers are 191,450,647,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,450,647,647 is 55609650.
Find LCM of 191,450,647,647 with Prime Factorization
647 | 191, 450, 647, 647 |
191, 450, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
647 x 191 x 450 x 1 x 1 = 55609650
Therefore, the lowest common multiple of 191,450,647,647 is 55609650.
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.
191 x 450 x 647 x 647 = 35979443550
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.
191 : 1, 191
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
647 : 1, 647
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,450,647,647, is 1.
Now, the common factors can be found like this.
191:191
450:2x 3x 3x 5x 5
647:647
647:647
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
647 = 647
Therefore, the value for common factors is 647.
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 = 35979443550/(1x647)
LCM = 35979443550/647
LCM = 55609650
Thus, we can understand that the LCM of 191,450,647,647 is 55609650.
