Calculate the LCM of 1,871,860,650

Given numbers are 1,871,860,650

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

The LCM of 1,871,860,650 is 3745300.

Find LCM of 1,871,860,650 with Prime Factorization


2 1, 871, 860, 650
5 1, 871, 430, 325
13 1, 871, 86, 65
1, 67, 86, 5

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

2 x 5 x 13 x 1 x 67 x 86 x 5 = 3745300

Therefore, the lowest common multiple of 1,871,860,650 is 3745300.

LCM Formula to Find Lowest Common Multiple of 1,871,860,650

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.

1 x 871 x 860 x 650 = 486889000

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.

1 : 1

871 : 1, 13, 67, 871

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,871,860,650, is 1.

Now, the common factors can be found like this.

1:

871:13x 67

860:2x 2x 5x 43

650:2x 5x 5x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 13 = 130

Therefore, the value for common factors is 130.

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 = 486889000/(1x130)

LCM = 486889000/130

LCM = 3745300

Thus, we can understand that the LCM of 1,871,860,650 is 3745300.
