Given numbers are 139,494,142,538,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,494,142,538,780 is 39343558020.
Find LCM of 139,494,142,538,780 with Prime Factorization
| 2 | 139, 494, 142, 538, 780 |
| 13 | 139, 247, 71, 269, 390 |
| 139, 19, 71, 269, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 139 x 19 x 71 x 269 x 30 = 39343558020
Therefore, the lowest common multiple of 139,494,142,538,780 is 39343558020.
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.
139 x 494 x 142 x 538 x 780 = 4091730034080
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.
139 : 1, 139
494 : 1, 2, 13, 19, 26, 38, 247, 494
142 : 1, 2, 71, 142
538 : 1, 2, 269, 538
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,494,142,538,780, is 1.
Now, the common factors can be found like this.
139:139
494:2x 13x 19
142:2x 71
538:2x 269
780:2x 2x 3x 5x 13
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 4091730034080/(1x104)
LCM = 4091730034080/104
LCM = 39343558020
Thus, we can understand that the LCM of 139,494,142,538,780 is 39343558020.
