Calculate the LCM of 817,545,985,304

Given numbers are 817,545,985,304

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

The LCM of 817,545,985,304 is 1403475280.

Find LCM of 817,545,985,304 with Prime Factorization


5 817, 545, 985, 304
19 817, 109, 197, 304
43, 109, 197, 16

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

5 x 19 x 43 x 109 x 197 x 16 = 1403475280

Therefore, the lowest common multiple of 817,545,985,304 is 1403475280.

LCM Formula to Find Lowest Common Multiple of 817,545,985,304

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.

817 x 545 x 985 x 304 = 133330151600

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.

817 : 1, 19, 43, 817

545 : 1, 5, 109, 545

985 : 1, 5, 197, 985

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,545,985,304, is 1.

Now, the common factors can be found like this.

817:19x 43

545:5x 109

985:5x 197

304:2x 2x 2x 2x 19

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

5x 19 = 95

Therefore, the value for common factors is 95.

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 = 133330151600/(1x95)

LCM = 133330151600/95

LCM = 1403475280

Thus, we can understand that the LCM of 817,545,985,304 is 1403475280.
