Given numbers are 770,986,802,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,986,802,641 is 97575334010.
Find LCM of 770,986,802,641 with Prime Factorization
2 | 770, 986, 802, 641 |
385, 493, 401, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 385 x 493 x 401 x 641 = 97575334010
Therefore, the lowest common multiple of 770,986,802,641 is 97575334010.
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.
770 x 986 x 802 x 641 = 390301336040
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
986 : 1, 2, 17, 29, 34, 58, 493, 986
802 : 1, 2, 401, 802
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,986,802,641, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
986:2x 17x 29
802:2x 401
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 390301336040/(1x4)
LCM = 390301336040/4
LCM = 97575334010
Thus, we can understand that the LCM of 770,986,802,641 is 97575334010.
