Calculate the LCM of 374,628,782,977,642

Given numbers are 374,628,782,977,642

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

The LCM of 374,628,782,977,642 is 847088298276.

Find LCM of 374,628,782,977,642 with Prime Factorization


2 374, 628, 782, 977, 642
17 187, 314, 391, 977, 321
11, 314, 23, 977, 321

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

2 x 17 x 11 x 314 x 23 x 977 x 321 = 847088298276

Therefore, the lowest common multiple of 374,628,782,977,642 is 847088298276.

LCM Formula to Find Lowest Common Multiple of 374,628,782,977,642

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.

374 x 628 x 782 x 977 x 642 = 115204008565536

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.

374 : 1, 2, 11, 17, 22, 34, 187, 374

628 : 1, 2, 4, 157, 314, 628

782 : 1, 2, 17, 23, 34, 46, 391, 782

977 : 1, 977

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,628,782,977,642, is 1.

Now, the common factors can be found like this.

374:2x 11x 17

628:2x 2x 157

782:2x 17x 23

977:977

642:2x 3x 107

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 2x 17 = 136

Therefore, the value for common factors is 136.

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 = 115204008565536/(1x136)

LCM = 115204008565536/136

LCM = 847088298276

Thus, we can understand that the LCM of 374,628,782,977,642 is 847088298276.
