Find LCM of 523,297,561,987,784 with Prime Factorization
| 3 | 523, 297, 561, 987, 784 |
| 7 | 523, 99, 187, 329, 784 |
| 11 | 523, 99, 187, 47, 112 |
| 523, 9, 17, 47, 112 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 523 x 9 x 17 x 47 x 112 = 97301823696
Therefore, the lowest common multiple of 523,297,561,987,784 is 97301823696.
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.
523 x 297 x 561 x 987 x 784 = 67430163821328
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.
523 : 1, 523
297 : 1, 3, 9, 11, 27, 33, 99, 297
561 : 1, 3, 11, 17, 33, 51, 187, 561
987 : 1, 3, 7, 21, 47, 141, 329, 987
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,297,561,987,784, is 1.
Now, the common factors can be found like this.
523:523
297:3x 3x 3x 11
561:3x 11x 17
987:3x 7x 47
784:2x 2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 11 = 693
Therefore, the value for common factors is 693.
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 = 67430163821328/(1x693)
LCM = 67430163821328/693
LCM = 97301823696
Thus, we can understand that the LCM of 523,297,561,987,784 is 97301823696.
