Calculate the LCM of 172,128,624,766

Given numbers are 172,128,624,766

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

The LCM of 172,128,624,766 is 82213248.

Find LCM of 172,128,624,766 with Prime Factorization


2 172, 128, 624, 766
2 86, 64, 312, 383
2 43, 32, 156, 383
2 43, 16, 78, 383
43, 8, 39, 383

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

2 x 2 x 2 x 2 x 43 x 8 x 39 x 383 = 82213248

Therefore, the lowest common multiple of 172,128,624,766 is 82213248.

LCM Formula to Find Lowest Common Multiple of 172,128,624,766

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 128 x 624 x 766 = 10523295744

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

766 : 1, 2, 383, 766

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,128,624,766, is 2.

Now, the common factors can be found like this.

172:2x 2x 43

128:2x 2x 2x 2x 2x 2x 2

624:2x 2x 2x 2x 3x 13

766:2x 383

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 10523295744/(2x64)

LCM = 10523295744/128

LCM = 82213248

Thus, we can understand that the LCM of 172,128,624,766 is 82213248.
