Calculate the LCM of 128,841,822,255

Given numbers are 128,841,822,255

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

The LCM of 128,841,822,255 is 3760682880.

Find LCM of 128,841,822,255 with Prime Factorization


2 128, 841, 822, 255
3 64, 841, 411, 255
64, 841, 137, 85

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

2 x 3 x 64 x 841 x 137 x 85 = 3760682880

Therefore, the lowest common multiple of 128,841,822,255 is 3760682880.

LCM Formula to Find Lowest Common Multiple of 128,841,822,255

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.

128 x 841 x 822 x 255 = 22564097280

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.

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

841 : 1, 29, 841

822 : 1, 2, 3, 6, 137, 274, 411, 822

255 : 1, 3, 5, 15, 17, 51, 85, 255

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,841,822,255, is 1.

Now, the common factors can be found like this.

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

841:29x 29

822:2x 3x 137

255:3x 5x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 22564097280/(1x6)

LCM = 22564097280/6

LCM = 3760682880

Thus, we can understand that the LCM of 128,841,822,255 is 3760682880.
