Given numbers are 943,753,775,420,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 943,753,775,420,431 is 6641155863300.
Find LCM of 943,753,775,420,431 with Prime Factorization
3 | 943, 753, 775, 420, 431 |
5 | 943, 251, 775, 140, 431 |
943, 251, 155, 28, 431 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 943 x 251 x 155 x 28 x 431 = 6641155863300
Therefore, the lowest common multiple of 943,753,775,420,431 is 6641155863300.
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.
943 x 753 x 775 x 420 x 431 = 99617337949500
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.
943 : 1, 23, 41, 943
753 : 1, 3, 251, 753
775 : 1, 5, 25, 31, 155, 775
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 943,753,775,420,431, is 1.
Now, the common factors can be found like this.
943:23x 41
753:3x 251
775:5x 5x 31
420:2x 2x 3x 5x 7
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 99617337949500/(1x15)
LCM = 99617337949500/15
LCM = 6641155863300
Thus, we can understand that the LCM of 943,753,775,420,431 is 6641155863300.
