Calculate the LCM of 847,454,289,803,424

Given numbers are 847,454,289,803,424

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

The LCM of 847,454,289,803,424 is 1719870815432.

Find LCM of 847,454,289,803,424 with Prime Factorization


2 847, 454, 289, 803, 424
11 847, 227, 289, 803, 212
77, 227, 289, 73, 212

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

2 x 11 x 77 x 227 x 289 x 73 x 212 = 1719870815432

Therefore, the lowest common multiple of 847,454,289,803,424 is 1719870815432.

LCM Formula to Find Lowest Common Multiple of 847,454,289,803,424

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.

847 x 454 x 289 x 803 x 424 = 37837157939504

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.

847 : 1, 7, 11, 77, 121, 847

454 : 1, 2, 227, 454

289 : 1, 17, 289

803 : 1, 11, 73, 803

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,454,289,803,424, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

454:2x 227

289:17x 17

803:11x 73

424:2x 2x 2x 53

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 37837157939504/(1x22)

LCM = 37837157939504/22

LCM = 1719870815432

Thus, we can understand that the LCM of 847,454,289,803,424 is 1719870815432.
