Given numbers are 878,213,892,781

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

The LCM of 878,213,892,781 is 917490684.

Find LCM of 878,213,892,781 with Prime Factorization

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

2 x 71 x 439 x 3 x 446 x 11 = 917490684

Therefore, the lowest common multiple of 878,213,892,781 is 917490684.

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.

878 x 213 x 892 x 781 = 130283677128

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.

878 : 1, 2, 439, 878

213 : 1, 3, 71, 213

892 : 1, 2, 4, 223, 446, 892

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,213,892,781, is 1.

Now, the common factors can be found like this.

878:2x 439

213:3x 71

892:2x 2x 223

781:11x 71

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 130283677128/(1x142)

LCM = 130283677128/142

LCM = 917490684

Thus, we can understand that the LCM of 878,213,892,781 is 917490684.
