Calculate the LCM of 280,565,365,985

Given numbers are 280,565,365,985

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

The LCM of 280,565,365,985 is 455014840.

Find LCM of 280,565,365,985 with Prime Factorization


5 280, 565, 365, 985
56, 113, 73, 197

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

5 x 56 x 113 x 73 x 197 = 455014840

Therefore, the lowest common multiple of 280,565,365,985 is 455014840.

LCM Formula to Find Lowest Common Multiple of 280,565,365,985

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.

280 x 565 x 365 x 985 = 56876855000

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

565 : 1, 5, 113, 565

365 : 1, 5, 73, 365

985 : 1, 5, 197, 985

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,565,365,985, is 5.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

565:5x 113

365:5x 73

985:5x 197

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 56876855000/(5x25)

LCM = 56876855000/125

LCM = 455014840

Thus, we can understand that the LCM of 280,565,365,985 is 455014840.
