The LCM of 256,650,121,657 is 6614150400.

Find LCM of 256,650,121,657 with Prime Factorization


2 256, 650, 121, 657
128, 325, 121, 657

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

2 x 128 x 325 x 121 x 657 = 6614150400

Therefore, the lowest common multiple of 256,650,121,657 is 6614150400.

LCM Formula to Find Lowest Common Multiple of 256,650,121,657

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.

256 x 650 x 121 x 657 = 13228300800

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.

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

121 : 1, 11, 121

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,650,121,657, is 1.

Now, the common factors can be found like this.

256:2x 2x 2x 2x 2x 2x 2x 2

650:2x 5x 5x 13

121:11x 11

657:3x 3x 73

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 = 13228300800/(1x2)

LCM = 13228300800/2

LCM = 6614150400

Thus, we can understand that the LCM of 256,650,121,657 is 6614150400.
