Find LCM of 254,630,850,731,685 with Prime Factorization
2 | 254, 630, 850, 731, 685 |
5 | 127, 315, 425, 731, 685 |
17 | 127, 63, 85, 731, 137 |
127, 63, 5, 43, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 127 x 63 x 5 x 43 x 137 = 40063807350
Therefore, the lowest common multiple of 254,630,850,731,685 is 40063807350.
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.
254 x 630 x 850 x 731 x 685 = 68108472495000
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.
254 : 1, 2, 127, 254
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
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
731 : 1, 17, 43, 731
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,630,850,731,685, is 1.
Now, the common factors can be found like this.
254:2x 127
630:2x 3x 3x 5x 7
850:2x 5x 5x 17
731:17x 43
685:5x 137
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 5x 5x 17 = 1700
Therefore, the value for common factors is 1700.
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 = 68108472495000/(1x1700)
LCM = 68108472495000/1700
LCM = 40063807350
Thus, we can understand that the LCM of 254,630,850,731,685 is 40063807350.
