Calculate the LCM of 542,856,790,189

Given numbers are 542,856,790,189

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

The LCM of 542,856,790,189 is 17318168280.

Find LCM of 542,856,790,189 with Prime Factorization


2 542, 856, 790, 189
271, 428, 395, 189

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

2 x 271 x 428 x 395 x 189 = 17318168280

Therefore, the lowest common multiple of 542,856,790,189 is 17318168280.

LCM Formula to Find Lowest Common Multiple of 542,856,790,189

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.

542 x 856 x 790 x 189 = 69272673120

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.

542 : 1, 2, 271, 542

856 : 1, 2, 4, 8, 107, 214, 428, 856

790 : 1, 2, 5, 10, 79, 158, 395, 790

189 : 1, 3, 7, 9, 21, 27, 63, 189

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,856,790,189, is 1.

Now, the common factors can be found like this.

542:2x 271

856:2x 2x 2x 107

790:2x 5x 79

189:3x 3x 3x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 69272673120/(1x4)

LCM = 69272673120/4

LCM = 17318168280

Thus, we can understand that the LCM of 542,856,790,189 is 17318168280.
