Given numbers are 780,572,820,676

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

The LCM of 780,572,820,676 is 4573140.

Find LCM of 780,572,820,676 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 11 x 41 x 13 = 4573140

Therefore, the lowest common multiple of 780,572,820,676 is 4573140.

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.

780 x 572 x 820 x 676 = 247315411200

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.

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

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,572,820,676, is 4.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

572:2x 2x 11x 13

820:2x 2x 5x 41

676:2x 2x 13x 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 2x 2x 2x 5x 13x 13 = 13520

Therefore, the value for common factors is 13520.

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 = 247315411200/(4x13520)

LCM = 247315411200/54080

LCM = 4573140

Thus, we can understand that the LCM of 780,572,820,676 is 4573140.
