Find LCM of 561,374,218,478,280 with Prime Factorization
2 | 561, 374, 218, 478, 280 |
11 | 561, 187, 109, 239, 140 |
17 | 51, 17, 109, 239, 140 |
3, 1, 109, 239, 140 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 3 x 1 x 109 x 239 x 140 = 4092091080
Therefore, the lowest common multiple of 561,374,218,478,280 is 4092091080.
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.
561 x 374 x 218 x 478 x 280 = 6121768255680
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
374 : 1, 2, 11, 17, 22, 34, 187, 374
218 : 1, 2, 109, 218
478 : 1, 2, 239, 478
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,374,218,478,280, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
374:2x 11x 17
218:2x 109
478:2x 239
280:2x 2x 2x 5x 7
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 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 6121768255680/(1x1496)
LCM = 6121768255680/1496
LCM = 4092091080
Thus, we can understand that the LCM of 561,374,218,478,280 is 4092091080.
