Calculate the LCM of 654,442,116,986

Given numbers are 654,442,116,986

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

The LCM of 654,442,116,986 is 8382972.

Find LCM of 654,442,116,986 with Prime Factorization


2 654, 442, 116, 986
17 327, 221, 58, 493
29 327, 13, 58, 29
327, 13, 2, 1

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

2 x 17 x 29 x 327 x 13 x 2 x 1 = 8382972

Therefore, the lowest common multiple of 654,442,116,986 is 8382972.

LCM Formula to Find Lowest Common Multiple of 654,442,116,986

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.

654 x 442 x 116 x 986 = 33062441568

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

442 : 1, 2, 13, 17, 26, 34, 221, 442

116 : 1, 2, 4, 29, 58, 116

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 654,442,116,986, is 2.

Now, the common factors can be found like this.

654:2x 3x 109

442:2x 13x 17

116:2x 2x 29

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 17x 29 = 1972

Therefore, the value for common factors is 1972.

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 = 33062441568/(2x1972)

LCM = 33062441568/3944

LCM = 8382972

Thus, we can understand that the LCM of 654,442,116,986 is 8382972.
