Given numbers are 991,910,790,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,910,790,681 is 48516476190.
Find LCM of 991,910,790,681 with Prime Factorization
2 | 991, 910, 790, 681 |
5 | 991, 455, 395, 681 |
991, 91, 79, 681 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 991 x 91 x 79 x 681 = 48516476190
Therefore, the lowest common multiple of 991,910,790,681 is 48516476190.
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 910 x 790 x 681 = 485164761900
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
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
790 : 1, 2, 5, 10, 79, 158, 395, 790
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,910,790,681, is 1.
Now, the common factors can be found like this.
991:991
910:2x 5x 7x 13
790:2x 5x 79
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 485164761900/(1x10)
LCM = 485164761900/10
LCM = 48516476190
Thus, we can understand that the LCM of 991,910,790,681 is 48516476190.
