Calculate the LCM of 688,657,229,229,370

Given numbers are 688,657,229,229,370

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

The LCM of 688,657,229,229,370 is 19149657840.

Find LCM of 688,657,229,229,370 with Prime Factorization


2 688, 657, 229, 229, 370
229 344, 657, 229, 229, 185
344, 657, 1, 1, 185

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

2 x 229 x 344 x 657 x 1 x 1 x 185 = 19149657840

Therefore, the lowest common multiple of 688,657,229,229,370 is 19149657840.

LCM Formula to Find Lowest Common Multiple of 688,657,229,229,370

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 657 x 229 x 229 x 370 = 8770543290720

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

657 : 1, 3, 9, 73, 219, 657

229 : 1, 229

229 : 1, 229

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,657,229,229,370, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

657:3x 3x 73

229:229

229:229

370:2x 5x 37

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

2x 229 = 458

Therefore, the value for common factors is 458.

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 = 8770543290720/(1x458)

LCM = 8770543290720/458

LCM = 19149657840

Thus, we can understand that the LCM of 688,657,229,229,370 is 19149657840.
