Given numbers are 621,224,410,748,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,224,410,748,811 is 4324699542240.
Find LCM of 621,224,410,748,811 with Prime Factorization
| 2 | 621, 224, 410, 748, 811 |
| 2 | 621, 112, 205, 374, 811 |
| 621, 56, 205, 187, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 621 x 56 x 205 x 187 x 811 = 4324699542240
Therefore, the lowest common multiple of 621,224,410,748,811 is 4324699542240.
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.
621 x 224 x 410 x 748 x 811 = 34597596337920
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
410 : 1, 2, 5, 10, 41, 82, 205, 410
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,224,410,748,811, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
224:2x 2x 2x 2x 2x 7
410:2x 5x 41
748:2x 2x 11x 17
811:811
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 2 = 8
Therefore, the value for common factors is 8.
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 = 34597596337920/(1x8)
LCM = 34597596337920/8
LCM = 4324699542240
Thus, we can understand that the LCM of 621,224,410,748,811 is 4324699542240.
