Given numbers are 991,520,273,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,520,273,817 is 8841345240.
Find LCM of 991,520,273,817 with Prime Factorization
13 | 991, 520, 273, 817 |
991, 40, 21, 817 |
Multiply the prime numbers at the bottom and the left side.
13 x 991 x 40 x 21 x 817 = 8841345240
Therefore, the lowest common multiple of 991,520,273,817 is 8841345240.
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.
991 x 520 x 273 x 817 = 114937488120
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.
991 : 1, 991
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
273 : 1, 3, 7, 13, 21, 39, 91, 273
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,520,273,817, is 1.
Now, the common factors can be found like this.
991:991
520:2x 2x 2x 5x 13
273:3x 7x 13
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 114937488120/(1x13)
LCM = 114937488120/13
LCM = 8841345240
Thus, we can understand that the LCM of 991,520,273,817 is 8841345240.
