Given numbers are 644,849,781,759,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,849,781,759,761 is 324959507796.
Find LCM of 644,849,781,759,761 with Prime Factorization
| 3 | 644, 849, 781, 759, 761 |
| 11 | 644, 283, 781, 253, 761 |
| 23 | 644, 283, 71, 23, 761 |
| 28, 283, 71, 1, 761 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 28 x 283 x 71 x 1 x 761 = 324959507796
Therefore, the lowest common multiple of 644,849,781,759,761 is 324959507796.
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.
644 x 849 x 781 x 759 x 761 = 246644266417164
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
849 : 1, 3, 283, 849
781 : 1, 11, 71, 781
759 : 1, 3, 11, 23, 33, 69, 253, 759
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,849,781,759,761, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
849:3x 283
781:11x 71
759:3x 11x 23
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 23 = 759
Therefore, the value for common factors is 759.
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 = 246644266417164/(1x759)
LCM = 246644266417164/759
LCM = 324959507796
Thus, we can understand that the LCM of 644,849,781,759,761 is 324959507796.
