Given numbers are 681,702,761,346,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,702,761,346,618 is 2160881512686.
Find LCM of 681,702,761,346,618 with Prime Factorization
| 2 | 681, 702, 761, 346, 618 |
| 3 | 681, 351, 761, 173, 309 |
| 227, 117, 761, 173, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 117 x 761 x 173 x 103 = 2160881512686
Therefore, the lowest common multiple of 681,702,761,346,618 is 2160881512686.
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.
681 x 702 x 761 x 346 x 618 = 77791734456696
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.
681 : 1, 3, 227, 681
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
761 : 1, 761
346 : 1, 2, 173, 346
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 681,702,761,346,618, is 1.
Now, the common factors can be found like this.
681:3x 227
702:2x 3x 3x 3x 13
761:761
346:2x 173
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 3 = 36
Therefore, the value for common factors is 36.
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 = 77791734456696/(1x36)
LCM = 77791734456696/36
LCM = 2160881512686
Thus, we can understand that the LCM of 681,702,761,346,618 is 2160881512686.
