Given numbers are 530,791,968,285,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 530,791,968,285,938 is 774903055080.
Find LCM of 530,791,968,285,938 with Prime Factorization
| 2 | 530, 791, 968, 285, 938 |
| 5 | 265, 791, 484, 285, 469 |
| 7 | 53, 791, 484, 57, 469 |
| 53, 113, 484, 57, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 53 x 113 x 484 x 57 x 67 = 774903055080
Therefore, the lowest common multiple of 530,791,968,285,938 is 774903055080.
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.
530 x 791 x 968 x 285 x 938 = 108486427711200
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.
530 : 1, 2, 5, 10, 53, 106, 265, 530
791 : 1, 7, 113, 791
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
285 : 1, 3, 5, 15, 19, 57, 95, 285
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,791,968,285,938, is 1.
Now, the common factors can be found like this.
530:2x 5x 53
791:7x 113
968:2x 2x 2x 11x 11
285:3x 5x 19
938:2x 7x 67
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 108486427711200/(1x140)
LCM = 108486427711200/140
LCM = 774903055080
Thus, we can understand that the LCM of 530,791,968,285,938 is 774903055080.
