Find LCM of 868,686,268,624,823 with Prime Factorization


2 868, 686, 268, 624, 823
2 434, 343, 134, 312, 823
7 217, 343, 67, 156, 823
31, 49, 67, 156, 823

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

2 x 2 x 7 x 31 x 49 x 67 x 156 x 823 = 365860093872

LCM Formula to Find Lowest Common Multiple of 868,686,268,624,823

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.

868 x 686 x 268 x 624 x 823 = 81952661027328

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.

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

268 : 1, 2, 4, 67, 134, 268

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

823 : 1, 823

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,686,268,624,823, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

686:2x 7x 7x 7

268:2x 2x 67

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

823:823

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 7 = 224

Therefore, the value for common factors is 224.

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 = 81952661027328/(1x224)

LCM = 81952661027328/224

LCM = 365860093872

Thus, we can understand that the LCM of 868,686,268,624,823 is 365860093872.
