Given numbers are 219,786,781,398

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

The LCM of 219,786,781,398 is 8917631382.

Find LCM of 219,786,781,398 with Prime Factorization

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

2 x 3 x 73 x 131 x 781 x 199 = 8917631382

Therefore, the lowest common multiple of 219,786,781,398 is 8917631382.

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.

219 x 786 x 781 x 398 = 53505788292

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.

219 : 1, 3, 73, 219

786 : 1, 2, 3, 6, 131, 262, 393, 786

781 : 1, 11, 71, 781

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,786,781,398, is 1.

Now, the common factors can be found like this.

219:3x 73

786:2x 3x 131

781:11x 71

398:2x 199

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 53505788292/(1x6)

LCM = 53505788292/6

LCM = 8917631382

Thus, we can understand that the LCM of 219,786,781,398 is 8917631382.
