Given numbers are 838,870,685,630

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

The LCM of 838,870,685,630 is 1048752810.

Find LCM of 838,870,685,630 with Prime Factorization

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

2 x 3 x 5 x 419 x 29 x 137 x 21 = 1048752810

Therefore, the lowest common multiple of 838,870,685,630 is 1048752810.

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.

838 x 870 x 685 x 630 = 314625843000

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.

838 : 1, 2, 419, 838

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

685 : 1, 5, 137, 685

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,870,685,630, is 1.

Now, the common factors can be found like this.

838:2x 419

870:2x 3x 5x 29

685:5x 137

630:2x 3x 3x 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 2x 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 314625843000/(1x300)

LCM = 314625843000/300

LCM = 1048752810

Thus, we can understand that the LCM of 838,870,685,630 is 1048752810.
