Given numbers are 153,642,618,932,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,642,618,932,822 is 215302420692.
Find LCM of 153,642,618,932,822 with Prime Factorization
| 2 | 153, 642, 618, 932, 822 |
| 3 | 153, 321, 309, 466, 411 |
| 51, 107, 103, 466, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 51 x 107 x 103 x 466 x 137 = 215302420692
Therefore, the lowest common multiple of 153,642,618,932,822 is 215302420692.
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.
153 x 642 x 618 x 932 x 822 = 46505322869472
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.
153 : 1, 3, 9, 17, 51, 153
642 : 1, 2, 3, 6, 107, 214, 321, 642
618 : 1, 2, 3, 6, 103, 206, 309, 618
932 : 1, 2, 4, 233, 466, 932
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,642,618,932,822, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
642:2x 3x 107
618:2x 3x 103
932:2x 2x 233
822:2x 3x 137
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 46505322869472/(1x216)
LCM = 46505322869472/216
LCM = 215302420692
Thus, we can understand that the LCM of 153,642,618,932,822 is 215302420692.
