Given numbers are 521,354,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,354,765 is 47030670.
Find LCM of 521,354,765 with Prime Factorization
| 3 | 521, 354, 765 |
| 521, 118, 255 |
Multiply the prime numbers at the bottom and the left side.
3 x 521 x 118 x 255 = 47030670
Therefore, the lowest common multiple of 521,354,765 is 47030670.
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.
521 x 354 x 765 = 141092010
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.
521 : 1, 521
354 : 1, 2, 3, 6, 59, 118, 177, 354
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 521,354,765, is 1.
Now, the common factors can be found like this.
521:521
354:2x 3x 59
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 141092010/(1x3)
LCM = 141092010/3
LCM = 47030670
Thus, we can understand that the LCM of 521,354,765 is 47030670.
