Given numbers are 743,561,536,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,561,536,781 is 15862616088.
Find LCM of 743,561,536,781 with Prime Factorization
11 | 743, 561, 536, 781 |
743, 51, 536, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 743 x 51 x 536 x 71 = 15862616088
Therefore, the lowest common multiple of 743,561,536,781 is 15862616088.
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.
743 x 561 x 536 x 781 = 174488776968
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.
743 : 1, 743
561 : 1, 3, 11, 17, 33, 51, 187, 561
536 : 1, 2, 4, 8, 67, 134, 268, 536
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,561,536,781, is 1.
Now, the common factors can be found like this.
743:743
561:3x 11x 17
536:2x 2x 2x 67
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.
11 = 11
Therefore, the value for common factors is 11.
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 = 174488776968/(1x11)
LCM = 174488776968/11
LCM = 15862616088
Thus, we can understand that the LCM of 743,561,536,781 is 15862616088.
