Calculate the LCM of 702,238,778,860

Given numbers are 702,238,778,860

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

The LCM of 702,238,778,860 is 13973401260.

Find LCM of 702,238,778,860 with Prime Factorization


2 702, 238, 778, 860
351, 119, 389, 430

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

2 x 351 x 119 x 389 x 430 = 13973401260

Therefore, the lowest common multiple of 702,238,778,860 is 13973401260.

LCM Formula to Find Lowest Common Multiple of 702,238,778,860

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.

702 x 238 x 778 x 860 = 111787210080

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.

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

238 : 1, 2, 7, 14, 17, 34, 119, 238

778 : 1, 2, 389, 778

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,238,778,860, is 2.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

238:2x 7x 17

778:2x 389

860:2x 2x 5x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 111787210080/(2x4)

LCM = 111787210080/8

LCM = 13973401260

Thus, we can understand that the LCM of 702,238,778,860 is 13973401260.
