Given numbers are 461,221,787,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 461,221,787,787 is 80180347.
Find LCM of 461,221,787,787 with Prime Factorization
787 | 461, 221, 787, 787 |
461, 221, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
787 x 461 x 221 x 1 x 1 = 80180347
Therefore, the lowest common multiple of 461,221,787,787 is 80180347.
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.
461 x 221 x 787 x 787 = 63101933089
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.
461 : 1, 461
221 : 1, 13, 17, 221
787 : 1, 787
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,221,787,787, is 1.
Now, the common factors can be found like this.
461:461
221:13x 17
787:787
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
787 = 787
Therefore, the value for common factors is 787.
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 = 63101933089/(1x787)
LCM = 63101933089/787
LCM = 80180347
Thus, we can understand that the LCM of 461,221,787,787 is 80180347.
