Calculate the LCM of 654,246,618,658

Given numbers are 654,246,618,658

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

The LCM of 654,246,618,658 is 908646018.

Find LCM of 654,246,618,658 with Prime Factorization


2 654, 246, 618, 658
3 327, 123, 309, 329
109, 41, 103, 329

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

2 x 3 x 109 x 41 x 103 x 329 = 908646018

Therefore, the lowest common multiple of 654,246,618,658 is 908646018.

LCM Formula to Find Lowest Common Multiple of 654,246,618,658

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 246 x 618 x 658 = 65422513296

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

246 : 1, 2, 3, 6, 41, 82, 123, 246

618 : 1, 2, 3, 6, 103, 206, 309, 618

658 : 1, 2, 7, 14, 47, 94, 329, 658

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,246,618,658, is 2.

Now, the common factors can be found like this.

654:2x 3x 109

246:2x 3x 41

618:2x 3x 103

658:2x 7x 47

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 65422513296/(2x36)

LCM = 65422513296/72

LCM = 908646018

Thus, we can understand that the LCM of 654,246,618,658 is 908646018.
