Given numbers are 7,638,989,781

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

The LCM of 7,638,989,781 is 313598054.

Find LCM of 7,638,989,781 with Prime Factorization

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

11 x 7 x 58 x 989 x 71 = 313598054

Therefore, the lowest common multiple of 7,638,989,781 is 313598054.

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.

7 x 638 x 989 x 781 = 3449578594

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.

7 : 1, 7

638 : 1, 2, 11, 22, 29, 58, 319, 638

989 : 1, 23, 43, 989

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,638,989,781, is 1.

Now, the common factors can be found like this.

7:7

638:2x 11x 29

989:23x 43

781:11x 71

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

11 = 11

Therefore, the value for common factors is 11.

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 = 3449578594/(1x11)

LCM = 3449578594/11

LCM = 313598054

Thus, we can understand that the LCM of 7,638,989,781 is 313598054.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 1, 600, 839, 354
