Given numbers are 685,545,995,630,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,545,995,630,272 is 254612428560.
Find LCM of 685,545,995,630,272 with Prime Factorization
| 2 | 685, 545, 995, 630, 272 |
| 5 | 685, 545, 995, 315, 136 |
| 137, 109, 199, 63, 136 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 137 x 109 x 199 x 63 x 136 = 254612428560
Therefore, the lowest common multiple of 685,545,995,630,272 is 254612428560.
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.
685 x 545 x 995 x 630 x 272 = 63653107140000
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.
685 : 1, 5, 137, 685
545 : 1, 5, 109, 545
995 : 1, 5, 199, 995
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
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,545,995,630,272, is 1.
Now, the common factors can be found like this.
685:5x 137
545:5x 109
995:5x 199
630:2x 3x 3x 5x 7
272:2x 2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 63653107140000/(1x250)
LCM = 63653107140000/250
LCM = 254612428560
Thus, we can understand that the LCM of 685,545,995,630,272 is 254612428560.
