Given numbers are 257,638,786,140

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

The LCM of 257,638,786,140 is 4510704660.

Find LCM of 257,638,786,140 with Prime Factorization

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

2 x 257 x 319 x 393 x 70 = 4510704660

Therefore, the lowest common multiple of 257,638,786,140 is 4510704660.

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.

257 x 638 x 786 x 140 = 18042818640

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.

257 : 1, 257

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,638,786,140, is 1.

Now, the common factors can be found like this.

257:257

638:2x 11x 29

786:2x 3x 131

140:2x 2x 5x 7

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 = 18042818640/(1x4)

LCM = 18042818640/4

LCM = 4510704660

Thus, we can understand that the LCM of 257,638,786,140 is 4510704660.
