Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 13 x 1 x 58 x 103 x 9 x 5 = 1174249440
Therefore, the lowest common multiple of 624,928,618,189,455 is 1174249440.
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.
624 x 928 x 618 x 189 x 455 = 30774729323520
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
618 : 1, 2, 3, 6, 103, 206, 309, 618
189 : 1, 3, 7, 9, 21, 27, 63, 189
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,928,618,189,455, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
928:2x 2x 2x 2x 2x 29
618:2x 3x 103
189:3x 3x 3x 7
455:5x 7x 13
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 2x 3x 3x 7x 13 = 26208
Therefore, the value for common factors is 26208.
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 = 30774729323520/(1x26208)
LCM = 30774729323520/26208
LCM = 1174249440
Thus, we can understand that the LCM of 624,928,618,189,455 is 1174249440.
