Given numbers are 769,451,981,390

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

The LCM of 769,451,981,390 is 44229827070.

Find LCM of 769,451,981,390 with Prime Factorization

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

3 x 769 x 451 x 327 x 130 = 44229827070

Therefore, the lowest common multiple of 769,451,981,390 is 44229827070.

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.

769 x 451 x 981 x 390 = 132689481210

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.

769 : 1, 769

451 : 1, 11, 41, 451

981 : 1, 3, 9, 109, 327, 981

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,451,981,390, is 1.

Now, the common factors can be found like this.

769:769

451:11x 41

981:3x 3x 109

390:2x 3x 5x 13

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

3 = 3

Therefore, the value for common factors is 3.

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 = 132689481210/(1x3)

LCM = 132689481210/3

LCM = 44229827070

Thus, we can understand that the LCM of 769,451,981,390 is 44229827070.
