Find LCM of 280,616,939,565,821 with Prime Factorization
2 | 280, 616, 939, 565, 821 |
2 | 140, 308, 939, 565, 821 |
2 | 70, 154, 939, 565, 821 |
5 | 35, 77, 939, 565, 821 |
7 | 7, 77, 939, 113, 821 |
1, 11, 939, 113, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 1 x 11 x 939 x 113 x 821 = 268310648760
Therefore, the lowest common multiple of 280,616,939,565,821 is 268310648760.
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.
280 x 616 x 939 x 565 x 821 = 75126981652800
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
939 : 1, 3, 313, 939
565 : 1, 5, 113, 565
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,616,939,565,821, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
616:2x 2x 2x 7x 11
939:3x 313
565:5x 113
821:821
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 7 = 280
Therefore, the value for common factors is 280.
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 = 75126981652800/(1x280)
LCM = 75126981652800/280
LCM = 268310648760
Thus, we can understand that the LCM of 280,616,939,565,821 is 268310648760.
