Given numbers are 847,636,139,474,495
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,636,139,474,495 is 88730652780.
Find LCM of 847,636,139,474,495 with Prime Factorization
| 2 | 847, 636, 139, 474, 495 |
| 3 | 847, 318, 139, 237, 495 |
| 11 | 847, 106, 139, 79, 165 |
| 77, 106, 139, 79, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 77 x 106 x 139 x 79 x 15 = 88730652780
Therefore, the lowest common multiple of 847,636,139,474,495 is 88730652780.
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.
847 x 636 x 139 x 474 x 495 = 17568669250440
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.
847 : 1, 7, 11, 77, 121, 847
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
139 : 1, 139
474 : 1, 2, 3, 6, 79, 158, 237, 474
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,636,139,474,495, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
636:2x 2x 3x 53
139:139
474:2x 3x 79
495:3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 17568669250440/(1x198)
LCM = 17568669250440/198
LCM = 88730652780
Thus, we can understand that the LCM of 847,636,139,474,495 is 88730652780.
