Given numbers are 556,784,577,497,861

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

The LCM of 556,784,577,497,861 is 549123634416.

Find LCM of 556,784,577,497,861 with Prime Factorization

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

2 x 2 x 7 x 139 x 28 x 577 x 71 x 123 = 549123634416

Therefore, the lowest common multiple of 556,784,577,497,861 is 549123634416.

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.

556 x 784 x 577 x 497 x 861 = 107628232345536

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.

556 : 1, 2, 4, 139, 278, 556

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

577 : 1, 577

497 : 1, 7, 71, 497

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,784,577,497,861, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

784:2x 2x 2x 2x 7x 7

577:577

497:7x 71

861:3x 7x 41

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 107628232345536/(1x196)

LCM = 107628232345536/196

LCM = 549123634416

Thus, we can understand that the LCM of 556,784,577,497,861 is 549123634416.
