Given numbers are 770,810,759,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,810,759,618 is 147754530.
Find LCM of 770,810,759,618 with Prime Factorization
| 2 | 770, 810, 759, 618 |
| 3 | 385, 405, 759, 309 |
| 5 | 385, 135, 253, 103 |
| 11 | 77, 27, 253, 103 |
| 7, 27, 23, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 7 x 27 x 23 x 103 = 147754530
Therefore, the lowest common multiple of 770,810,759,618 is 147754530.
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 810 x 759 x 618 = 292553969400
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
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
759 : 1, 3, 11, 23, 33, 69, 253, 759
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,810,759,618, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
810:2x 3x 3x 3x 3x 5
759:3x 11x 23
618:2x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 292553969400/(1x1980)
LCM = 292553969400/1980
LCM = 147754530
Thus, we can understand that the LCM of 770,810,759,618 is 147754530.
