The LCM of 635,490,722,266,820 is 1842132460.
Find LCM of 635,490,722,266,820 with Prime Factorization
| 2 | 635, 490, 722, 266, 820 |
| 5 | 635, 245, 361, 133, 410 |
| 7 | 127, 49, 361, 133, 82 |
| 19 | 127, 7, 361, 19, 82 |
| 127, 7, 1, 19, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 127 x 7 x 1 x 19 x 82 = 1842132460
Therefore, the lowest common multiple of 635,490,722,266,820 is 1842132460.
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.
635 x 490 x 722 x 266 x 820 = 49000723436000
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.
635 : 1, 5, 127, 635
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
722 : 1, 2, 19, 38, 361, 722
266 : 1, 2, 7, 14, 19, 38, 133, 266
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,490,722,266,820, is 1.
Now, the common factors can be found like this.
635:5x 127
490:2x 5x 7x 7
722:2x 19x 19
266:2x 7x 19
820:2x 2x 5x 41
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 2x 5x 5x 7x 19 = 26600
Therefore, the value for common factors is 26600.
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 = 49000723436000/(1x26600)
LCM = 49000723436000/26600
LCM = 1842132460
Thus, we can understand that the LCM of 635,490,722,266,820 is 1842132460.
