Calculate the LCM of 656,646,644,146,651

Given numbers are 656,646,644,146,651

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

The LCM of 656,646,644,146,651 is 231599728752.

Find LCM of 656,646,644,146,651 with Prime Factorization


2 656, 646, 644, 146, 651
2 328, 323, 322, 73, 651
7 164, 323, 161, 73, 651
164, 323, 23, 73, 93

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

2 x 2 x 7 x 164 x 323 x 23 x 73 x 93 = 231599728752

Therefore, the lowest common multiple of 656,646,644,146,651 is 231599728752.

LCM Formula to Find Lowest Common Multiple of 656,646,644,146,651

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.

656 x 646 x 644 x 146 x 651 = 25939169620224

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

646 : 1, 2, 17, 19, 34, 38, 323, 646

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

146 : 1, 2, 73, 146

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,646,644,146,651, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

646:2x 17x 19

644:2x 2x 7x 23

146:2x 73

651:3x 7x 31

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 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 25939169620224/(1x112)

LCM = 25939169620224/112

LCM = 231599728752

Thus, we can understand that the LCM of 656,646,644,146,651 is 231599728752.
