Given numbers are 784,158,718,489

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

The LCM of 784,158,718,489 is 10872926736.

Find LCM of 784,158,718,489 with Prime Factorization

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

2 x 392 x 79 x 359 x 489 = 10872926736

Therefore, the lowest common multiple of 784,158,718,489 is 10872926736.

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 158 x 718 x 489 = 43491706944

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

158 : 1, 2, 79, 158

718 : 1, 2, 359, 718

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,158,718,489, is 1.

Now, the common factors can be found like this.

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

158:2x 79

718:2x 359

489:3x 163

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 = 43491706944/(1x4)

LCM = 43491706944/4

LCM = 10872926736

Thus, we can understand that the LCM of 784,158,718,489 is 10872926736.
