Given numbers are 771,748,803,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,748,803,781 is 2989077564.
Find LCM of 771,748,803,781 with Prime Factorization
11 | 771, 748, 803, 781 |
771, 68, 73, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 771 x 68 x 73 x 71 = 2989077564
Therefore, the lowest common multiple of 771,748,803,781 is 2989077564.
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.
771 x 748 x 803 x 781 = 361678385244
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.
771 : 1, 3, 257, 771
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
803 : 1, 11, 73, 803
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,748,803,781, is 1.
Now, the common factors can be found like this.
771:3x 257
748:2x 2x 11x 17
803:11x 73
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 361678385244/(1x121)
LCM = 361678385244/121
LCM = 2989077564
Thus, we can understand that the LCM of 771,748,803,781 is 2989077564.
