Given numbers are 287,389,764,780

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

The LCM of 287,389,764,780 is 16632574140.

Find LCM of 287,389,764,780 with Prime Factorization

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

2 x 2 x 287 x 389 x 191 x 195 = 16632574140

Therefore, the lowest common multiple of 287,389,764,780 is 16632574140.

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.

287 x 389 x 764 x 780 = 66530296560

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.

287 : 1, 7, 41, 287

389 : 1, 389

764 : 1, 2, 4, 191, 382, 764

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,389,764,780, is 1.

Now, the common factors can be found like this.

287:7x 41

389:389

764:2x 2x 191

780:2x 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.

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 = 66530296560/(1x4)

LCM = 66530296560/4

LCM = 16632574140

Thus, we can understand that the LCM of 287,389,764,780 is 16632574140.
