Given numbers are 436,253,647,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,253,647,561 is 3639833076.
Find LCM of 436,253,647,561 with Prime Factorization
11 | 436, 253, 647, 561 |
436, 23, 647, 51 |
Multiply the prime numbers at the bottom and the left side.
11 x 436 x 23 x 647 x 51 = 3639833076
Therefore, the lowest common multiple of 436,253,647,561 is 3639833076.
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.
436 x 253 x 647 x 561 = 40038163836
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.
436 : 1, 2, 4, 109, 218, 436
253 : 1, 11, 23, 253
647 : 1, 647
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,253,647,561, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
253:11x 23
647:647
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 40038163836/(1x11)
LCM = 40038163836/11
LCM = 3639833076
Thus, we can understand that the LCM of 436,253,647,561 is 3639833076.
