Calculate the LCM of 871,290,781,635

Given numbers are 871,290,781,635

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

The LCM of 871,290,781,635 is 25053644330.

Find LCM of 871,290,781,635 with Prime Factorization


5 871, 290, 781, 635
871, 58, 781, 127

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

5 x 871 x 58 x 781 x 127 = 25053644330

Therefore, the lowest common multiple of 871,290,781,635 is 25053644330.

LCM Formula to Find Lowest Common Multiple of 871,290,781,635

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.

871 x 290 x 781 x 635 = 125268221650

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.

871 : 1, 13, 67, 871

290 : 1, 2, 5, 10, 29, 58, 145, 290

781 : 1, 11, 71, 781

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,290,781,635, is 1.

Now, the common factors can be found like this.

871:13x 67

290:2x 5x 29

781:11x 71

635:5x 127

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

5 = 5

Therefore, the value for common factors is 5.

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 = 125268221650/(1x5)

LCM = 125268221650/5

LCM = 25053644330

Thus, we can understand that the LCM of 871,290,781,635 is 25053644330.
