Given numbers are 169,611,638,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,611,638,781 is 359802014.
Find LCM of 169,611,638,781 with Prime Factorization
| 11 | 169, 611, 638, 781 |
| 13 | 169, 611, 58, 71 |
| 13, 47, 58, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 13 x 47 x 58 x 71 = 359802014
Therefore, the lowest common multiple of 169,611,638,781 is 359802014.
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.
169 x 611 x 638 x 781 = 51451688002
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.
169 : 1, 13, 169
611 : 1, 13, 47, 611
638 : 1, 2, 11, 22, 29, 58, 319, 638
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,611,638,781, is 1.
Now, the common factors can be found like this.
169:13x 13
611:13x 47
638:2x 11x 29
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 51451688002/(1x143)
LCM = 51451688002/143
LCM = 359802014
Thus, we can understand that the LCM of 169,611,638,781 is 359802014.
