LCM Formula to Find Lowest Common Multiple of 780,620,300,637,436

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 620 x 300 x 637 x 436 = 40293358560000

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

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300

637 : 1, 7, 13, 49, 91, 637

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,620,300,637,436, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

620:2x 2x 5x 31

300:2x 2x 3x 5x 5

637:7x 7x 13

436:2x 2x 109

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 2x 2x 3x 5x 5x 13 = 62400

Therefore, the value for common factors is 62400.

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 = 40293358560000/(1x62400)

LCM = 40293358560000/62400

LCM = 645726900

Thus, we can understand that the LCM of 780,620,300,637,436 is 645726900.
