The LCM of 628,988,152,171 is 2792088.

Find LCM of 628,988,152,171 with Prime Factorization


2 628, 988, 152, 171
2 314, 494, 76, 171
19 157, 247, 38, 171
157, 13, 2, 9

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

2 x 2 x 19 x 157 x 13 x 2 x 9 = 2792088

Therefore, the lowest common multiple of 628,988,152,171 is 2792088.

LCM Formula to Find Lowest Common Multiple of 628,988,152,171

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.

628 x 988 x 152 x 171 = 16127100288

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.

628 : 1, 2, 4, 157, 314, 628

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

152 : 1, 2, 4, 8, 19, 38, 76, 152

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,988,152,171, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

988:2x 2x 13x 19

152:2x 2x 2x 19

171:3x 3x 19

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 19x 19 = 5776

Therefore, the value for common factors is 5776.

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 = 16127100288/(1x5776)

LCM = 16127100288/5776

LCM = 2792088

Thus, we can understand that the LCM of 628,988,152,171 is 2792088.
