Calculate the LCM of 865,464,942,565

Given numbers are 865,464,942,565

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

The LCM of 865,464,942,565 is 21361583280.

Find LCM of 865,464,942,565 with Prime Factorization


2 865, 464, 942, 565
5 865, 232, 471, 565
173, 232, 471, 113

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

2 x 5 x 173 x 232 x 471 x 113 = 21361583280

Therefore, the lowest common multiple of 865,464,942,565 is 21361583280.

LCM Formula to Find Lowest Common Multiple of 865,464,942,565

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.

865 x 464 x 942 x 565 = 213615832800

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.

865 : 1, 5, 173, 865

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

942 : 1, 2, 3, 6, 157, 314, 471, 942

565 : 1, 5, 113, 565

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,464,942,565, is 1.

Now, the common factors can be found like this.

865:5x 173

464:2x 2x 2x 2x 29

942:2x 3x 157

565:5x 113

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 213615832800/(1x10)

LCM = 213615832800/10

LCM = 21361583280

Thus, we can understand that the LCM of 865,464,942,565 is 21361583280.
