Calculate the LCM of 847,460,702,787

Given numbers are 847,460,702,787

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

The LCM of 847,460,702,787 is 107627459940.

Find LCM of 847,460,702,787 with Prime Factorization


2 847, 460, 702, 787
847, 230, 351, 787

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

2 x 847 x 230 x 351 x 787 = 107627459940

Therefore, the lowest common multiple of 847,460,702,787 is 107627459940.

LCM Formula to Find Lowest Common Multiple of 847,460,702,787

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.

847 x 460 x 702 x 787 = 215254919880

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.

847 : 1, 7, 11, 77, 121, 847

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

787 : 1, 787

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,460,702,787, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

460:2x 2x 5x 23

702:2x 3x 3x 3x 13

787:787

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

2 = 2

Therefore, the value for common factors is 2.

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 = 215254919880/(1x2)

LCM = 215254919880/2

LCM = 107627459940

Thus, we can understand that the LCM of 847,460,702,787 is 107627459940.
