Given numbers are 823,154,892,618,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,154,892,618,220 is 87334109940.
Find LCM of 823,154,892,618,220 with Prime Factorization
| 2 | 823, 154, 892, 618, 220 |
| 2 | 823, 77, 446, 309, 110 |
| 11 | 823, 77, 223, 309, 55 |
| 823, 7, 223, 309, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 823 x 7 x 223 x 309 x 5 = 87334109940
Therefore, the lowest common multiple of 823,154,892,618,220 is 87334109940.
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.
823 x 154 x 892 x 618 x 220 = 15370803349440
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.
823 : 1, 823
154 : 1, 2, 7, 11, 14, 22, 77, 154
892 : 1, 2, 4, 223, 446, 892
618 : 1, 2, 3, 6, 103, 206, 309, 618
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,154,892,618,220, is 1.
Now, the common factors can be found like this.
823:823
154:2x 7x 11
892:2x 2x 223
618:2x 3x 103
220:2x 2x 5x 11
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 15370803349440/(1x176)
LCM = 15370803349440/176
LCM = 87334109940
Thus, we can understand that the LCM of 823,154,892,618,220 is 87334109940.
