Given numbers are 495,856,821,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 495,856,821,748 is 5913860040.
Find LCM of 495,856,821,748 with Prime Factorization
| 2 | 495, 856, 821, 748 |
| 2 | 495, 428, 821, 374 |
| 11 | 495, 214, 821, 187 |
| 45, 214, 821, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 45 x 214 x 821 x 17 = 5913860040
Therefore, the lowest common multiple of 495,856,821,748 is 5913860040.
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.
495 x 856 x 821 x 748 = 260209841760
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
856 : 1, 2, 4, 8, 107, 214, 428, 856
821 : 1, 821
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,856,821,748, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
856:2x 2x 2x 107
821:821
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 260209841760/(1x44)
LCM = 260209841760/44
LCM = 5913860040
Thus, we can understand that the LCM of 495,856,821,748 is 5913860040.
