Given numbers are 784,557,655,557

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

The LCM of 784,557,655,557 is 286030640.

Find LCM of 784,557,655,557 with Prime Factorization

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

557 x 784 x 1 x 655 x 1 = 286030640

Therefore, the lowest common multiple of 784,557,655,557 is 286030640.

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.

784 x 557 x 655 x 557 = 159319066480

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.

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

557 : 1, 557

655 : 1, 5, 131, 655

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,557,655,557, is 1.

Now, the common factors can be found like this.

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

557:557

655:5x 131

557:557

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

557 = 557

Therefore, the value for common factors is 557.

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 = 159319066480/(1x557)

LCM = 159319066480/557

LCM = 286030640

Thus, we can understand that the LCM of 784,557,655,557 is 286030640.
