Given numbers are 770,821,162,935
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,821,162,935 is 870498090.
Find LCM of 770,821,162,935 with Prime Factorization
| 2 | 770, 821, 162, 935 |
| 5 | 385, 821, 81, 935 |
| 11 | 77, 821, 81, 187 |
| 7, 821, 81, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 821 x 81 x 17 = 870498090
Therefore, the lowest common multiple of 770,821,162,935 is 870498090.
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 821 x 162 x 935 = 95754789900
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
821 : 1, 821
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,821,162,935, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
821:821
162:2x 3x 3x 3x 3
935:5x 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.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 95754789900/(1x110)
LCM = 95754789900/110
LCM = 870498090
Thus, we can understand that the LCM of 770,821,162,935 is 870498090.
