Find LCM of 311,690,250,220,618 with Prime Factorization
2 | 311, 690, 250, 220, 618 |
3 | 311, 345, 125, 110, 309 |
5 | 311, 115, 125, 110, 103 |
311, 23, 25, 22, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 311 x 23 x 25 x 22 x 103 = 12156523500
Therefore, the lowest common multiple of 311,690,250,220,618 is 12156523500.
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.
311 x 690 x 250 x 220 x 618 = 7293914100000
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.
311 : 1, 311
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
250 : 1, 2, 5, 10, 25, 50, 125, 250
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
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 311,690,250,220,618, is 1.
Now, the common factors can be found like this.
311:311
690:2x 3x 5x 23
250:2x 5x 5x 5
220:2x 2x 5x 11
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 2x 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 7293914100000/(1x600)
LCM = 7293914100000/600
LCM = 12156523500
Thus, we can understand that the LCM of 311,690,250,220,618 is 12156523500.
