Calculate the LCM of 874,639,156,247

Given numbers are 874,639,156,247

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

The LCM of 874,639,156,247 is 14520636.

Find LCM of 874,639,156,247 with Prime Factorization


2 874, 639, 156, 247
3 437, 639, 78, 247
13 437, 213, 26, 247
19 437, 213, 2, 19
23, 213, 2, 1

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

2 x 3 x 13 x 19 x 23 x 213 x 2 x 1 = 14520636

Therefore, the lowest common multiple of 874,639,156,247 is 14520636.

LCM Formula to Find Lowest Common Multiple of 874,639,156,247

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.

874 x 639 x 156 x 247 = 21519582552

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.

874 : 1, 2, 19, 23, 38, 46, 437, 874

639 : 1, 3, 9, 71, 213, 639

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,639,156,247, is 1.

Now, the common factors can be found like this.

874:2x 19x 23

639:3x 3x 71

156:2x 2x 3x 13

247:13x 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 3x 13x 19 = 1482

Therefore, the value for common factors is 1482.

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 = 21519582552/(1x1482)

LCM = 21519582552/1482

LCM = 14520636

Thus, we can understand that the LCM of 874,639,156,247 is 14520636.
