Calculate the LCM of 981,622,504,455

Given numbers are 981,622,504,455

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 981,622,504,455 is 1110531240.

Find LCM of 981,622,504,455 with Prime Factorization


2 981, 622, 504, 455
3 981, 311, 252, 455
3 327, 311, 84, 455
7 109, 311, 28, 455
109, 311, 4, 65

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 3 x 7 x 109 x 311 x 4 x 65 = 1110531240

Therefore, the lowest common multiple of 981,622,504,455 is 1110531240.

LCM Formula to Find Lowest Common Multiple of 981,622,504,455

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.

981 x 622 x 504 x 455 = 139926936240

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.

981 : 1, 3, 9, 109, 327, 981

622 : 1, 2, 311, 622

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

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 981,622,504,455, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

622:2x 311

504:2x 2x 2x 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 3x 3x 7 = 126

Therefore, the value for common factors is 126.

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 = 139926936240/(1x126)

LCM = 139926936240/126

LCM = 1110531240

Thus, we can understand that the LCM of 981,622,504,455 is 1110531240.
