Calculate the LCM of 821,988,524,428

Given numbers are 821,988,524,428

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

The LCM of 821,988,524,428 is 11369861516.

Find LCM of 821,988,524,428 with Prime Factorization


2 821, 988, 524, 428
2 821, 494, 262, 214
821, 247, 131, 107

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

2 x 2 x 821 x 247 x 131 x 107 = 11369861516

Therefore, the lowest common multiple of 821,988,524,428 is 11369861516.

LCM Formula to Find Lowest Common Multiple of 821,988,524,428

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.

821 x 988 x 524 x 428 = 181917784256

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.

821 : 1, 821

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

524 : 1, 2, 4, 131, 262, 524

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,988,524,428, is 1.

Now, the common factors can be found like this.

821:821

988:2x 2x 13x 19

524:2x 2x 131

428:2x 2x 107

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 2 = 16

Therefore, the value for common factors is 16.

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 = 181917784256/(1x16)

LCM = 181917784256/16

LCM = 11369861516

Thus, we can understand that the LCM of 821,988,524,428 is 11369861516.
