Calculate the LCM of 285,868,988,274

Given numbers are 285,868,988,274

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

The LCM of 285,868,988,274 is 440583780.

Find LCM of 285,868,988,274 with Prime Factorization


2 285, 868, 988, 274
2 285, 434, 494, 137
19 285, 217, 247, 137
15, 217, 13, 137

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

2 x 2 x 19 x 15 x 217 x 13 x 137 = 440583780

Therefore, the lowest common multiple of 285,868,988,274 is 440583780.

LCM Formula to Find Lowest Common Multiple of 285,868,988,274

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.

285 x 868 x 988 x 274 = 66968734560

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

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

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,868,988,274, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

868:2x 2x 7x 31

988:2x 2x 13x 19

274:2x 137

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 19 = 152

Therefore, the value for common factors is 152.

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 = 66968734560/(1x152)

LCM = 66968734560/152

LCM = 440583780

Thus, we can understand that the LCM of 285,868,988,274 is 440583780.
