Given numbers are 618,756,968,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 618,756,968,862 is 8121788136.
Find LCM of 618,756,968,862 with Prime Factorization
| 2 | 618, 756, 968, 862 |
| 2 | 309, 378, 484, 431 |
| 3 | 309, 189, 242, 431 |
| 103, 63, 242, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 63 x 242 x 431 = 8121788136
Therefore, the lowest common multiple of 618,756,968,862 is 8121788136.
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.
618 x 756 x 968 x 862 = 389845830528
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
862 : 1, 2, 431, 862
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,756,968,862, is 2.
Now, the common factors can be found like this.
618:2x 3x 103
756:2x 2x 3x 3x 3x 7
968:2x 2x 2x 11x 11
862:2x 431
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 389845830528/(2x24)
LCM = 389845830528/48
LCM = 8121788136
Thus, we can understand that the LCM of 618,756,968,862 is 8121788136.
