Given numbers are 980,861,707,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,861,707,561 is 2276638980.
Find LCM of 980,861,707,561 with Prime Factorization
3 | 980, 861, 707, 561 |
7 | 980, 287, 707, 187 |
140, 41, 101, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 140 x 41 x 101 x 187 = 2276638980
Therefore, the lowest common multiple of 980,861,707,561 is 2276638980.
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.
980 x 861 x 707 x 561 = 334665930060
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
861 : 1, 3, 7, 21, 41, 123, 287, 861
707 : 1, 7, 101, 707
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 980,861,707,561, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
861:3x 7x 41
707:7x 101
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.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 334665930060/(1x147)
LCM = 334665930060/147
LCM = 2276638980
Thus, we can understand that the LCM of 980,861,707,561 is 2276638980.
