Calculate the LCM of 688,508,206,254

Given numbers are 688,508,206,254

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

The LCM of 688,508,206,254 is 8999728.

Find LCM of 688,508,206,254 with Prime Factorization


2 688, 508, 206, 254
2 344, 254, 103, 127
127 172, 127, 103, 127
172, 1, 103, 1

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

2 x 2 x 127 x 172 x 1 x 103 x 1 = 8999728

Therefore, the lowest common multiple of 688,508,206,254 is 8999728.

LCM Formula to Find Lowest Common Multiple of 688,508,206,254

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.

688 x 508 x 206 x 254 = 18287447296

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

508 : 1, 2, 4, 127, 254, 508

206 : 1, 2, 103, 206

254 : 1, 2, 127, 254

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,508,206,254, is 2.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

508:2x 2x 127

206:2x 103

254:2x 127

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 127 = 1016

Therefore, the value for common factors is 1016.

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 = 18287447296/(2x1016)

LCM = 18287447296/2032

LCM = 8999728

Thus, we can understand that the LCM of 688,508,206,254 is 8999728.
