Calculate the LCM of 812,922,544,145

Given numbers are 812,922,544,145

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

The LCM of 812,922,544,145 is 254545760.

Find LCM of 812,922,544,145 with Prime Factorization


2 812, 922, 544, 145
2 406, 461, 272, 145
29 203, 461, 136, 145
7, 461, 136, 5

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

2 x 2 x 29 x 7 x 461 x 136 x 5 = 254545760

Therefore, the lowest common multiple of 812,922,544,145 is 254545760.

LCM Formula to Find Lowest Common Multiple of 812,922,544,145

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.

812 x 922 x 544 x 145 = 59054616320

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

922 : 1, 2, 461, 922

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,922,544,145, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

922:2x 461

544:2x 2x 2x 2x 2x 17

145:5x 29

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 29 = 232

Therefore, the value for common factors is 232.

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 = 59054616320/(1x232)

LCM = 59054616320/232

LCM = 254545760

Thus, we can understand that the LCM of 812,922,544,145 is 254545760.
