Given numbers are 803,438,689,428

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

The LCM of 803,438,689,428 is 710394828.

Find LCM of 803,438,689,428 with Prime Factorization

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

2 x 73 x 11 x 3 x 689 x 214 = 710394828

Therefore, the lowest common multiple of 803,438,689,428 is 710394828.

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.

803 x 438 x 689 x 428 = 103717644888

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.

803 : 1, 11, 73, 803

438 : 1, 2, 3, 6, 73, 146, 219, 438

689 : 1, 13, 53, 689

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,438,689,428, is 1.

Now, the common factors can be found like this.

803:11x 73

438:2x 3x 73

689:13x 53

428:2x 2x 107

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

2x 73 = 146

Therefore, the value for common factors is 146.

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 = 103717644888/(1x146)

LCM = 103717644888/146

LCM = 710394828

Thus, we can understand that the LCM of 803,438,689,428 is 710394828.
