The LCM of 526,393,630,765 is 368991630.
Find LCM of 526,393,630,765 with Prime Factorization
| 2 | 526, 393, 630, 765 |
| 3 | 263, 393, 315, 765 |
| 3 | 263, 131, 105, 255 |
| 5 | 263, 131, 35, 85 |
| 263, 131, 7, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 263 x 131 x 7 x 17 = 368991630
Therefore, the lowest common multiple of 526,393,630,765 is 368991630.
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.
526 x 393 x 630 x 765 = 99627740100
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.
526 : 1, 2, 263, 526
393 : 1, 3, 131, 393
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
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 526,393,630,765, is 1.
Now, the common factors can be found like this.
526:2x 263
393:3x 131
630:2x 3x 3x 5x 7
765:3x 3x 5x 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 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 99627740100/(1x270)
LCM = 99627740100/270
LCM = 368991630
Thus, we can understand that the LCM of 526,393,630,765 is 368991630.
