Calculate the LCM of 172,688,203,292

Given numbers are 172,688,203,292

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

The LCM of 172,688,203,292 is 10195472.

Find LCM of 172,688,203,292 with Prime Factorization


2 172, 688, 203, 292
2 86, 344, 203, 146
43 43, 172, 203, 73
1, 4, 203, 73

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

2 x 2 x 43 x 1 x 4 x 203 x 73 = 10195472

Therefore, the lowest common multiple of 172,688,203,292 is 10195472.

LCM Formula to Find Lowest Common Multiple of 172,688,203,292

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.

172 x 688 x 203 x 292 = 7014484736

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.

172 : 1, 2, 4, 43, 86, 172

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

203 : 1, 7, 29, 203

292 : 1, 2, 4, 73, 146, 292

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,688,203,292, is 1.

Now, the common factors can be found like this.

172:2x 2x 43

688:2x 2x 2x 2x 43

203:7x 29

292:2x 2x 73

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 2x 43 = 688

Therefore, the value for common factors is 688.

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 = 7014484736/(1x688)

LCM = 7014484736/688

LCM = 10195472

Thus, we can understand that the LCM of 172,688,203,292 is 10195472.
