Find LCM of 921,242,499,385,765 with Prime Factorization
3 | 921, 242, 499, 385, 765 |
5 | 307, 242, 499, 385, 255 |
11 | 307, 242, 499, 77, 51 |
307, 22, 499, 7, 51 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 307 x 22 x 499 x 7 x 51 = 198524340630
Therefore, the lowest common multiple of 921,242,499,385,765 is 198524340630.
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.
921 x 242 x 499 x 385 x 765 = 32756516203950
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.
921 : 1, 3, 307, 921
242 : 1, 2, 11, 22, 121, 242
499 : 1, 499
385 : 1, 5, 7, 11, 35, 55, 77, 385
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 921,242,499,385,765, is 1.
Now, the common factors can be found like this.
921:3x 307
242:2x 11x 11
499:499
385:5x 7x 11
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.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 32756516203950/(1x165)
LCM = 32756516203950/165
LCM = 198524340630
Thus, we can understand that the LCM of 921,242,499,385,765 is 198524340630.
