Find LCM of 231,742,618,220 with Prime Factorization
| 2 | 231, 742, 618, 220 |
| 3 | 231, 371, 309, 110 |
| 7 | 77, 371, 103, 110 |
| 11 | 11, 53, 103, 110 |
| 1, 53, 103, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 53 x 103 x 10 = 25220580
Therefore, the lowest common multiple of 231,742,618,220 is 25220580.
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.
231 x 742 x 618 x 220 = 23303815920
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
742 : 1, 2, 7, 14, 53, 106, 371, 742
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 231,742,618,220, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
742:2x 7x 53
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 3x 7x 11 = 924
Therefore, the value for common factors is 924.
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 = 23303815920/(1x924)
LCM = 23303815920/924
LCM = 25220580
Thus, we can understand that the LCM of 231,742,618,220 is 25220580.
