Given numbers are 173,781,630,824,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,781,630,824,790 is 2770524492120.
Find LCM of 173,781,630,824,790 with Prime Factorization
| 2 | 173, 781, 630, 824, 790 |
| 5 | 173, 781, 315, 412, 395 |
| 173, 781, 63, 412, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 173 x 781 x 63 x 412 x 79 = 2770524492120
Therefore, the lowest common multiple of 173,781,630,824,790 is 2770524492120.
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.
173 x 781 x 630 x 824 x 790 = 55410489842400
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.
173 : 1, 173
781 : 1, 11, 71, 781
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
824 : 1, 2, 4, 8, 103, 206, 412, 824
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,781,630,824,790, is 1.
Now, the common factors can be found like this.
173:173
781:11x 71
630:2x 3x 3x 5x 7
824:2x 2x 2x 103
790:2x 5x 79
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 5 = 20
Therefore, the value for common factors is 20.
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 = 55410489842400/(1x20)
LCM = 55410489842400/20
LCM = 2770524492120
Thus, we can understand that the LCM of 173,781,630,824,790 is 2770524492120.
