Calculate the LCM of 778,238,104,986

Given numbers are 778,238,104,986

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

The LCM of 778,238,104,986 is 139613656.

Find LCM of 778,238,104,986 with Prime Factorization


2 778, 238, 104, 986
17 389, 119, 52, 493
389, 7, 52, 29

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

2 x 17 x 389 x 7 x 52 x 29 = 139613656

Therefore, the lowest common multiple of 778,238,104,986 is 139613656.

LCM Formula to Find Lowest Common Multiple of 778,238,104,986

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.

778 x 238 x 104 x 986 = 18987457216

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.

778 : 1, 2, 389, 778

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

104 : 1, 2, 4, 8, 13, 26, 52, 104

986 : 1, 2, 17, 29, 34, 58, 493, 986

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,238,104,986, is 2.

Now, the common factors can be found like this.

778:2x 389

238:2x 7x 17

104:2x 2x 2x 13

986:2x 17x 29

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

2x 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 18987457216/(2x68)

LCM = 18987457216/136

LCM = 139613656

Thus, we can understand that the LCM of 778,238,104,986 is 139613656.
