Calculate the LCM of 689,732,174,179

Given numbers are 689,732,174,179

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

The LCM of 689,732,174,179 is 2618070468.

Find LCM of 689,732,174,179 with Prime Factorization


2 689, 732, 174, 179
3 689, 366, 87, 179
689, 122, 29, 179

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

2 x 3 x 689 x 122 x 29 x 179 = 2618070468

Therefore, the lowest common multiple of 689,732,174,179 is 2618070468.

LCM Formula to Find Lowest Common Multiple of 689,732,174,179

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.

689 x 732 x 174 x 179 = 15708422808

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.

689 : 1, 13, 53, 689

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

174 : 1, 2, 3, 6, 29, 58, 87, 174

179 : 1, 179

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,732,174,179, is 1.

Now, the common factors can be found like this.

689:13x 53

732:2x 2x 3x 61

174:2x 3x 29

179:179

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 15708422808/(1x6)

LCM = 15708422808/6

LCM = 2618070468

Thus, we can understand that the LCM of 689,732,174,179 is 2618070468.
