Given numbers are 117,173,692,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 117,173,692,639 is 5748444.
Find LCM of 117,173,692,639 with Prime Factorization
| 3 | 117, 173, 692, 639 |
| 3 | 39, 173, 692, 213 |
| 173 | 13, 173, 692, 71 |
| 13, 1, 4, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 173 x 13 x 1 x 4 x 71 = 5748444
Therefore, the lowest common multiple of 117,173,692,639 is 5748444.
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.
117 x 173 x 692 x 639 = 8950327308
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.
117 : 1, 3, 9, 13, 39, 117
173 : 1, 173
692 : 1, 2, 4, 173, 346, 692
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,173,692,639, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
173:173
692:2x 2x 173
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 173 = 1557
Therefore, the value for common factors is 1557.
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 = 8950327308/(1x1557)
LCM = 8950327308/1557
LCM = 5748444
Thus, we can understand that the LCM of 117,173,692,639 is 5748444.
