Calculate the LCM of 623,128,422,491

Given numbers are 623,128,422,491

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

The LCM of 623,128,422,491 is 8261558144.

Find LCM of 623,128,422,491 with Prime Factorization


2 623, 128, 422, 491
623, 64, 211, 491

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

2 x 623 x 64 x 211 x 491 = 8261558144

Therefore, the lowest common multiple of 623,128,422,491 is 8261558144.

LCM Formula to Find Lowest Common Multiple of 623,128,422,491

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.

623 x 128 x 422 x 491 = 16523116288

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.

623 : 1, 7, 89, 623

128 : 1, 2, 4, 8, 16, 32, 64, 128

422 : 1, 2, 211, 422

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,128,422,491, is 1.

Now, the common factors can be found like this.

623:7x 89

128:2x 2x 2x 2x 2x 2x 2

422:2x 211

491:491

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

2 = 2

Therefore, the value for common factors is 2.

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 = 16523116288/(1x2)

LCM = 16523116288/2

LCM = 8261558144

Thus, we can understand that the LCM of 623,128,422,491 is 8261558144.
